PLEASE ANSWER THE QUESTION 100 POINTS

it is -1/2 through out the line

Step-by-step explanation:

Slope = rise / run

rise = 2

run = -4

therefore slope

-2/4

-1/2

in a linear function, slope is the same through out the line

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
