Answer 2

Slope of the line is -1. You know how to get that using (y2-y1)/(x2-x1)?

Answer 3

Now use the point slope formula: y-y1=m(x-x1) where m = -1
x1, y1 is any point on your line. Lets use (1,-3). So x1=1, y1=-3

Answer 4

y+3 = -1(x-1)
y+3 = -x +1
To get the x int set y=0
0+3 = -x + 1
x = 1-3
x = -2
Answer is -2

Answer 5

If you want me to go back over any step here let me know.

Answer 6

oh i see what i was doing wrong haha LMFAO

Answer 7
