find the slope of the line. what does the slope tell you about the speed of the car? the slope is. the speed of the car is? miles per hour.
Answer
Explanation:
Step1: Select two points on the line
Let's choose the points ((1, 40)) and ((2, 80)) from the graph.
Step2: Use the slope formula (m=\frac{y_2 - y_1}{x_2 - x_1})
Substitute (x_1 = 1,y_1 = 40,x_2 = 2,y_2 = 80) into the formula: [m=\frac{80 - 40}{2 - 1}=\frac{40}{1}=40]
Answer:
The slope is (40). The speed of the car is (40) miles per hour.
