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

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.
