Slope-intercept form is:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0)

1. y = 4x + 1

Slope: 4

y-intercept: 1

2. y = -3x

Slope: -3

y-intercept: 0

3. -x + y = 4 First isolate the "y". Add x on both sides

-x + x + y = 4 + x

y = 4 + x

Slope: 1

y-intercept: 4

4. y = 5/6x - 3

Slope:
(5)/(6)

y-intercept: -3

5. y + 3x = -7 Isolate the "y". Subtract 3x on both sides

y + 3x - 3x = -7 - 3x

y = -7 - 3x

Slope: -3

y-intercept: -7

6. y = 1/5x + 2

Slope:
(1)/(5)

y-intercept: 2
