Answer:
x=8, y=25. As a point it's (8,25)
Step-by-step explanation:
here is the system:
y=x+17
y=3x+1
notice how both of the equations equal y. Therefore, we can substitute one expression as y in the other expression. (It'll equal y=y, which is a true statement)
so it'll be:
3x+1=x+17
subtract 1 from both sides
3x=x+16
subtract x from both sides
2x=16
divide by 2
x=8
now, substitute 8 as x into one of the equations and solve for y
let's take the first one for example
y=8+17
y=25
so the answer is x=8, y=25. As a point it's (8,25)

Answer:
y = -3/2x + 6
Step-by-step explanation:
Parallel lines have the same slope so slope is -3/2
Using (4,0)
y = mx + b
0 = -3/2(4) + b
0 = -6 + b
b = 6
so y = -3/2x + 6
