8x - 10 = 86 {combined like terms}

8x = 96 {added 10 to both sides}

x = 12 {divided both sides by 8}

3x - 5 = 31 {substituted 12, in for x, into 3x - 5}


width = 12 in.

length = 31 in.

Pleaseeeee helppppp ASAPPPPP

Hello.

To find the slope, use the formula:

m= (y2-y1) / (x2-x1)

Note: The 2s and 1s are NOT exponents or constants. They are simply markers.

So:

m= (5-(-4)) / (2-0)

m= (5+4) / 2

m = 9/2

Note: The order of the coordinates don't matter as long as y2 is aligned with x2 etc.

Example: (okay)

m= ((-4)-5) / (0-2)

m= -9/ -2

m= 9/2 because a negative multiplied or divided by a negative makes a positive.

Now, let's see what's not okay:

(2,5)(0,-4)

m= (5-(-4)) / (0-2)

NOT. OKAY. since the 1s and 2s aren't aligned.

Hope that helped.
