What is the slope of the line that contains the points (-1 -1) and (3,15)

The slope is 4

Step-by-step explanation:

( -1 , -1 ) , ( 3 , 15 )

to find the slope just do the formula y1-y2/x2-x1

-1 - 15/-1 - 3

-1 - 15 = -16

-1 - 3 = -4

-16/-4

4

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
