Question

Find the equation of the line with x-intercept 4 and y-intercept 8. help!!

Answer 1

y = -2x + 8

Answer 2

ok can u explain how u got that plzz?

Answer 3

First we have to find the gradient(m):
m = (y2 - y1) / (x2 - x1)
m = (0 - 8)/(0 - 4)
m = -2

Using the general for finding an eqn of a line:
y - y1 = m(x - x1)
y - 0 = -2(x - 4)
y = -2x + 8
