• 1/3

• 2

• 3

• -3

Which form is used to write the equation of a line given a point and a slope?

• General form

• Point-slope form

• Standard form

• Slope-intercept form

How do you convert from point-slope form to slope-intercept form?

• Subtract the slope from both sides.

• Distribute the slope and solve for y.

• Add the slope to both sides.

• Multiply both sides by the slope.
