-2x-y=-5 In slope intercept form please! :)
schepotkina [342]

Answer:

-2x - y = -5 in slop intercept form would be <u>y = -2x + 5 </u>

Step-by-step explanation:

-2x - y = -5

first add -2x to the left side to move it to the right side because whatever you do to one side u do to the other.

-y = -5 + 2x

divide by -1 on the whole equation

y = -2x + 5 is your answer.
