Which equation has an � −intercept of (5,0) and a � −intercept of (0, −2.5)? a. � + 2.5 = 5(� − 0) b. � − 2.5 = 5(� − 0) c. � = 1 2 (� − 5) d. � = 1 2 (� + 5)

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
