Question

Put the following equation of a line into a slope-intercept form, simplifying all fractions.

3y-3x=21

Answer 1

Answer: y = x + 7

Explanation:

To find the slope-intercept form (y=mx+c), we have to make 'y' the subject of the equation:

3y - 3x = 21 [add 3x to both sides]

3y = 3x + 21 [divide all terms by 3]

y = x + 7

∴ 3y - 3x = 21 in slope-intercept form is y = x + 7.
