Question

Find the equation of the line with slope 3 which meets x_axis in the same point as the line x+4y=8

Answer 1

Answer:

3x-y=24

Step-by-step explanation:

the point which the line x+4y=8 meet x_axis :

set y=0   ∴x=8

the point is (8,0)

the line with slope 3 equation :

$\frac{y-0}{x-8}$=3

∴ 3x-24=y

∴3x-y=24
