Question

Put the following equation of a line into slope-intercept form, simplifying all fractions. 2y-2x=4

Answer 1

y = x + 2

Explanation:

Slope intercept form is y=mx + b. where m is the slope and b is the y-intercept (the value of y when x=0).

2y-2x=4

2y= 2x + 4 [add 2x to both sides]

y = x + 2 [divide both sides by 2]

This is a straight line with slope of 1 and a y-intercept of +2. See the attached graph.
