Simply plug in -15 for x in our given equation.

-x + 2y = -1

-(-15) + 2y = -1

Simplify.

15 + 2y = -1

Subtract 15 from both sides.

2y = -1 - 15

Simplify.

2y = -16

Divide both sides by 2

Y = -8

Hope I helped :)

Makovka662 [10]

The expression equivalent to the expression -90 - 60w is -30(3 + 2w),  (-9 - 6w)10 and  -20(4.5 + 3w)

We need to find the expressions that are equivalent to given expression

We solve the expression and check,

A) -30(3 + 2w)

-90 - 60w

Yes it is equivalent.

B) (-9 - 6w)10

-90 - 60w

Yes it is equivalent.

C) -3(30 - 20w)

-90 + 60w

No it is not equivalent.

D)(6 + 4w)15

90 + 60w

No it is not equivalent.

E) -20(4.5 + 3w)

-90 - 60w

Yes it is equivalent.

Therefore, The expression equivalent to the expression -90 - 60w is -30(3 + 2w),  (-9 - 6w)10 and  -20(4.5 + 3w)

Slope = 2/5 ; Passes through (-4, -7) ; Point-slope form

point-slope form : y-y₁=m(x-x₁)

Simply plug everything in :)

Remember !! m=slope

y - (-7) = 2/3(x - (-4))

Simplify.

y + 7 = 2/3(x + 4)

*Some teachers want this simplified more so here's the simplest answer : 

y + 7 = 2/3x + 8/3 *
