Answer:
8) y = x/2 + 6
9) x = -(7/4)
Step-by-step explanation:
for (8), start with point-slope form and enter -2, 5, and 1/2 into the appropriate places:
y-5 = (1/2)(x- -2)
simplify by distributing (1/2)
y-5 = x/2 + 1
add 5 to both sides to get yourself in slope-intercept form
y = x/2 + 6
for 9, start by distributing the 3 and the 2
6x-12 = 10x-8+3
combine like terms
6x-12 = 10x-5
subtract 6x from both sides
-12 = 4x-5
add 5 to both sides
-7=4x
divide both sides by 4
-(7/4) = x
