Slope-Intercept form of an equation

y = mx + b

3

Multiple Choice

What does m in y = mx + b tell us?

1

Slope

2

Y-intercept

4

Multiple Choice

What does b in y = mx + b tell us?

1

Slope

2

Y-intercept

5

Slope-Intercept Form

  • y = mx + b

  • m tells us the slope (how much the pattern moves by)

  • b tells us the y-intercept (where the line touches the y-axis; where the pattern begins)

  • y is by itself on one side of the equation

6

Standard Form

  • Ax + By = C

  • x and y, multiplied by coefficients, are on the same side of the equation

  • We can set x to 0 and find the y-int using By = C

  • We can set y to 0 and find the x-int using Ax = C

Recap:

Slope-intercept form:

y = mx + b



Standard form:

Ax + By = C
