Question

Find the slope and y-intercept of this linear function:
2x + x = 4(y - 1)

Answer 1

• slope: 3/4
• y-intercept: 1

Explanation:

Solve for y to put the equation in slope-intercept form.

3x = 4y -4 . . . . . eliminate parentheses, collect terms

3x +4 = 4y . . . . . add 4

y = 3/4x +1 . . . . . divide by 4

The slope is the x-coefficient: 3/4.

The y-intercept is the constant: 1.
