• x

• b

In slope-intercept form, which variable represents the slope?

• y

• m

• x

• b

Find the slope:

• 3/4
• 4/3
• -3/4
• -4/3

• subtract 3x to both sides

• divide by 3x on both sides

• add 3x on both sides

• divide by 3 on both sides

All of the variables cancelled out of the equation and you are left with the following statement: 0 = -5.

What is the answer?

• 0

• no solutions

• infinite solutions

• 0 and -5

• -5x - 3

• -5x + 3

• -8x

• -2x

The ordered pairs represent points on a line. Without solving, identify the y-intercept.
