Question

find the equation of the line with x-intercept 4 and y-intercept 8 plzz help!!!

Answer 1

For x-intercept 4 means when y is 0 x is 4 => (4,0)
For y-intercept 8 means when x is 0 y is 8 => (0,8)

To find the slope,
m = (y2 -y1) / (x2 - x1)
y2 = 8, y1 = 0
x2 = 0, x1 = 4
m = (8 - 0) / (0 - 4)
m = -2

To find the equation of a line,
y - y1 = m(x - x1)
Taking any one of the coordinates,
(0, 8)
y - 8 = -2(x - 0)
y - 8 = -2x
y = -2x + 8

equation of the line is y = -2x + 8
