Answer:
First question: (0, 1) (-4, 0)
Step-by-step explanation:
FIRST QUESTION:
y=3x+1
y=x-7
In the first equation of the first question, (y=3x+1) the 3 represents the slope and the 1 represents the y-intercept. Therefore, your first coordinate is (0, 1).
To figure out the second coordinate, do this:
Substitute y for x-7
x-7=3x+1
Combine like terms
x=3x+8
-3x+x=8
-2x=8
Divide the entire equation by -2
x=-4
Therefore, your second coordinate is (-4, 0).
SECOND QUESTION:
I am really sorry, I can't see the second question very well. It's a little too blurry and I have bad eyesight.
Hope this helps a little.
