Question

What is the equation of the line with slope of – 5 and passes through (2, – 3)?

Answer 1

y = -5x + 7

Explanation:

Graph has a slope of -5, which is the gradient

y = -5x + c

To find c you have to sub in the point (2, -3)

-3 = -5(2) + c

-3 + 10 = c

c = 7

Hence equation is:

y = -5x + 7
