Fthe line passing through the points (1, a) and (5, −2) is parallel to the line passing through the points (2, 8) and (−5, a + 7), what is the value of a?

Step-by-step explanation:

Line 1:  (1, a) and (5, −2)

slope of the   line is

Line 2:  (2, 8) and (−5, a + 7)

slope of the   line is

when the lines are parallel then slopes are equal

cross multiply it

subtract 4a from both sides

divide both sides by 3

step-by-step explanation:

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
