What is the slope of the line that goes through (-5,5) and (5,-7)

y2-y1/x2-x1

=-7-5/5-(-5)

=-12/10

=-6/5

Step-by-step explanation:

Given two points on on a line to find the slope we use the formula y2-y1/x2-x1 , hence the answer above.

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
