Answer:
X going up by 4s Y going up by 16s
Explanation:
X
-7+4=-3
-3+4=1
1+4=5
And so on...
Y
-28+16=-12
-12+16=4
4+16=20
And so on...
If this is meant for slope then you would use the formula m=y2-y1/x2-x1
You can use -12 to equal y2 and -21 to equal y1
You can use -3 to equal x2 and -7 to equal x1
Now your equation should be...
m=-12-(-21)/-3-(-7)
m=9/4
9 is the rise
4 is the run
the slope is 9/4
Y-intercept for would be...
m=9/4x
Hope this helps :)
