Question

Hi! I don't really get these two questions, I would really really appreciate your help. Please if you don't mind include work in your answer and an explanation. Please and thank you.

Answer 1

1)4x+2y=8
When y=0 (x-intercept)
4x=8
x=8/4
x=2
When x=0 (y-intercept)
2y=8
y=8/2
y=4

2) *Do same again*
-5x+3y=-15
-5x=-15
x=3
3y=-15
y=-5

Answer 2

1. x intercept - (2,0)
y intercept - (0,4)

2. x intercept - (3,0)
