I believe it is option 2, sorry if incorrect
Answer:
x = 2, y= 3
Step-by-step explanation:
y = -2x+7
y = 5x-7
Since the equations are both equal to y, set them equal to each other
-2x+7 = 5x-7
Add 2x to each side
-2x+7 +2x= 5x+2x-7
7 = 7x -7
Add 7 to each side
7+7 = 7x
14 = 7x
Divide by 7
14/7 = 7x/7
2 = x
Now find y
y = 5x-7
y = 5*2 -7
y = 10-7
y =3
The answer would be 0, as the slope of a line is definite as it pitch, or rate of increase. So if the line were going up to the right it would be positive, to the left, negative. An undefined slope would be the exact opposite of that slope. The slope you have, when written in y=mx+b is y=4
