What is an equation for 2,0 and -2,2

y=-1/2x OR y=-1/2x+b

Step-by-step explanation:

Slope=Rise/Run=(2-0)/(-2-2)=2/-4=-1/2

Equation is y=-1/2x+b

b, the y-intercept, can stand for anything, even 0

step-by-step explanation:

1699/ 8548

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
