Y = 0.2X + 30. - is your equation


So your slop n = 0.2

y-intercept : 30

Thank You! Though I have a question can you please explain It so I can understand how you did it why is the slope 0.2? When in the word problem it says “ it costs .20”

Jennifer, the key here is to understand how to create a line equation based on data given to you and what each coefficient in that equation actually means. The slop is simply one of those coefficients. Thus, you don’t need a slope, you need to understand how to create an equation.
