Solution for the equations is (-8, 2).

Step-by-step explanation:

  • Step 1: Given equations are 2x + y = -7y and y = x + 10. Simplify the equations.

⇒ 2x + 8y = 0 -------- (1)

⇒ x - y = - 10 ---------- (2)

  • Step 2: Multiply eq(2) with 2 to make coefficients of x equal

⇒ 2x - 2y = -20 ------- (3)

  • Step 3: Subtract eq(3) from eq(1)

⇒ 10y = 20

⇒ y = 2

  • Step 4: Find the value of x by substituting the value of y in eq(2)

⇒ x = - 10 + 2 = -8

-x+y=-2 in slope intercept form​
elixir [45]

Answer:

y = x - 2

Step-by-step explanation:

Slope intercept form is: y = mx + b, where m is the slope and b is the y- intercept. In this question, we are given everything, and all we need to do is rearrange the terms.

-x + y = -2

Add x to both sides

y = x - 2

In this equation, the slope is 1 and the y intercept is -2.
