Question

The equation of the line which passes through the point (3, 7) and has a gradient of 3 is:

Answer 1

y = mx + b, where m is gradient and b is y-intercept

y = 3

y = 3x + b

To find b use the coordinate (3, 7) to find b

7 = 3(3) + b

b = 7 - 9

b = -2

Therefore, the equation will be:

Therefore, the equation will be:y = 3x - 2
