Extra toppings are $1.50 extra. Write an equation in slope intercept form that describes this situation. Step 1: Slope intercept form: y = mx + b Step 2: b = $10 (amount is constant) m = $1.50 (this amount will change depending on the amount of toppings you buy.) Step 3: y = mx + b y = $1.50x + 10**Example 2: Jon walks 4 miles per day. Next week he wants to**walk an extra 2 miles per day. Write an equation in slope intercept form that describes this situation. Step 1: Slope intercept form: y = mx + b Step 2: b = 4 (amount is constant) m = 2 (this amount will change depending on the amount of miles he actually walks.) Step 3: y = mx + b y = 2x + 4**You do: You are in Tucson, AZ and a taxi company charges $5**for just using the taxi services and an additional $0.75 per mile. Write an equation that you could use to find the cost of a taxi ride in Tucson, AZ. b = $5 (amount is constant) m = $0.75 (this amount will change depending on the amount of miles.) y = mx + b y = $0.75x + $5**You do: A plumber charges a fee of $75 to make a house call.**They also charge $30 per hour for labor. Write an equation that you could use to find the amount a plumber charges for making a house call based on the number of hours of labor. b = $75 (amount is constant) m = $30 (this amount will change depending on the amount of hours it takes them.) y = mx + b y = $30x + $75**Key concepts**Slope of a line measures the steepness of the line. Rise means how many units you move up or down from point to point. On the graph that would be a change in the y values. Runmeans how far left or right you move from point to point. On the graph, that would mean a change of x values. in y in x**Positive slope so both numbers (rise and run) are positive.**rise run**Negative slope so the number associated with the rise is**negative. rise run**Slope Formula Given Two Points**Given two pointsand Note that we use the letter m to represent slope.**Example 1: Find the slope of the straight line that passes**through (-5, 2) and (4, -7). Plug in x and y values into slope formula Simplify The slope of the line is -1.**Find the slope of the straight line that passes through**(1, 1) and (5, 1). The slope of the line is 0.**Find the slope of the straight line that passes through (3,**4) and (3, 6). The slope of the line is undefined.**Practice**• Find the slope of the line**Key concepts**• x-intercept is where the graph crosses the x axis. To find the x-intercept (linear equation) find the value of x when y = 0.The x-coordinate of this point is always 0. • y-intercept is where the graph crosses the y axis. To find the y-intercept, find the value of y when x = 0.The y-coordinate of this point is always 0.**To find the y-intercept, find the point on the graph, where**x = 0 and find y. To find the x-intercept, find the point on the graph, where y = 0 and find x.**For the following slides identify the y-intercept and the**x-intercept.**Slope Intercept Form**y = mx + b**Identify the slope and y-intercept of the line with the**given equation. y = 3x + 4 y = 1/3x + 7 Slope y-intercept 3x + y = 4**What is the slope and y-intercept of the graphed line?

How do you translate between the different displays?**Writing equations in slope intercept form ( y = mx + b )**The equation below is written in the slope intercept form y = mx + b y = 2x + 1 2x – 2y = 8**Writing equations in slope intercept form ( y = mx + b )**However, 2x – 2y = 8 is not written in the correct form. 2x – 2y = 8 Isolate y -2x -2x -2y = -2x + 8 Divide both sides by -2 ÷2 ÷ -2 y = -x + 4**You do: Write the following equation in slope intercept**2x + 3y = 9**Write down the following equations.
