Answer:
(-8,0) (-1,0) (4,0)
Step-by-step explanation:
Just look at where y=0
-8, -1 and 4
look at where the line meets the x-axis and at what point
x=1 & y=6 or (1,6)
3x-x+5=7 Substitute the 2nd equation in for y
2x+5=7 Do 3x-x to get 2x
2x=2 Subtract 5 from both sides
x=1 Divide 2 from both sides
y=1+5 Insert 1 as x
y=6 Add 1+5 to solve for y
