Question

Which equation represents the line that has a slope of 1/2
and contains the point (0, 3)?

Answer 1

y - 3 = 1/2 (x) ......

Answer 2

y = x/2 +3

Explanation:

The equation of a straight line is

y = mx +c , where m is the gradient, and c is the y intercept.

We are told the gradient is 1/2, and the y-intercept is the y-value when x =0, so i.e. the y-intercept is 3.

So y = x/2 +3
