Question

Find the equation of a line in gradient intercept form that passes through (1,4) and has a gradient of -2.

Show working out ty ;)

Answer 1

y = -2x + 6

Explanation:

y = mx + c

Where m is the gradient and c is the y-intercept

m = -2

y = -2x + c

When x = 1, y = 4

4 = -2(1) + c

c = 6

y = -2x + 6
