Question

Write each equation in slope-intercept form of the equation of a line. Underline the slope and circle the y-intercept in each equation.

3x+4y–12=0
2x+y=1

Answer 1

First equation: 3x+4y-12=0. Solving for 4y, we get 4y = -3x + 12, from which

y = (-3/4)x - 3. The slope is -3/4 and the y-int. is -3.

Second equation: 2x + y = 1. y = -2x + 1. The slope is -2 and the y-int. is 1.
