Question

Match each equation with the graphs

Answer 1

i) y = 2x + 3

ii) y = 3x + 3

iii) y = 5x + 5

iv) y = 5x + 2

Explanation:

i) The first graph has the slope (m) = 2 and the y-intercept(b) = 3

Therefore, the equation of the line is y = 2x + 3

ii) The second graph has the slope (m) = 3 and the y-intercept (b) = 3

Therefore, the equation of the line is y = 3x + 3

iii) The third graph has the slope (m) = 5 and the y-intercept (b) = 5.

Therefore, the equation of the line is y = 5x + 5

iv) The fourth graph has the slope (m) = 5 and the y-intercept (b) = 2

Therefore, the equation of the line is y = 5x + 2

Answer 2

Look at them end of equation and that will be your y intercept for example y = 5x+3 the 3 is the y intercept in that equation so that will be where the line crosses the y intercept. All of your graphs have different y intercepts so you should get it right
