What's the slope of -x+2y=5

miv72 [106K]

Answer:

Slope = (1/2)

Step-by-step explanation:

Rearrange the equation into the y = mx + b format.

-x + 2y = 5

2y = x + 5

y = (1/2)x + (5/2)

m represents slope, which is (1/2) in this question.

Set as x and x-2

Create an equation of 3(x) = (x-2)-10

Solve, x = -6.

So, x-2 = -8.

Why is (3,-5) not a solution to -x+4y=-15

Olegator [25]

C) It doesn’t satisfy either the top or bottom equations.

When we plug them into the top equation:
$- 3 + 4( - 5) = - 15$
Simplify:
$- 3 + ( - 20) = - 15 \\ \\ - 23= - 15$
Because the statement of -23 = -15 is wrong, the solution pair is wrong for the top equation.

When we plug them into the bottom equation:
$- 2(3) - 3( - 5) = - 8$
Simplify:
$- 6 - ( - 15) = - 8 \\ \\ 9 = - 8$
9 = -8 is not a valid statement, so the pair doesn't satisfy both of the equations.
