(7,-11),(16,7)
What is the slope?

The slope is 2

Step-by-step explanation:

Given two points, we can find the slope from

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

   (7--11)/( 16-7)

   (7+11)/(16-7)

   18/9

    2

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
