Question

State the slope and y-intercept for the graph of the equation -8x + y = -12.

Show your work!!

Answer 1

Slope is 8 and Y-Intercept is -12

Explanation:

Move the -8x over to the right side by adding it, You are now at

y=-12+8x

Move these around and you are now at

Y=8x-12

Answer 2

Explanation:

Remark

• y must have a numerical coefficient of 1. This equation does. If it does not, then you must divide through by whatever is in front of the y.
• To read the slope, you must have x and its coefficient on opposite sides of the equal sign.
• So you get
• y = 8x - 12 when you add 8x to both sides
• Next, the y intercept is found when x = 0
• y = 8x - 12
• y = 8(0) - 12
• y = - 12
• The y intercept is -12 or in point form (0, - 12)

Answer

slope = 8

y intercept = - 12
