Write the equation 12 − y = 2x − 5 in slope-intercept form. What are the slope and y-intercept? A. y=2x−17,m=2, y-intercept (0,−

MrRissso [65]

Answer:

Step-by-step explanation:

12-y=2x-5

+5 +5 ( add 5 to both sides)

17-y=2x

-17 -17 (Subtract 17 to get y by itself)

-y=2x-17

divide by -1 because y cant be negative

y=-2x+17

m=-2 and y-intercept= 17

I hope thats right :)
