Get Equations into Slope-Intercept Form

Convert the standard form equation into slope-intercept form.
x + y = -1

• y = x - 1

• y = 27, 239, 430

• y = -1x

• y = -x - 1

Convert the standard form equation into slope-intercept form.
3x - 2y = 0

• y = (3/2)x

• y = -3x + 2

• x = 0

• y = 27, 239, 430

Convert the standard form equation into slope-intercept form.
5x - 4y = -20

• y = (5/4)x + 5

• y = -5x - 4

• x = 20

• y = 27, 239, 430

What is the first step in solving a system by graphing?

• Write both linear equations in slope-intercept form

• Get x by itself

• Compare the slopes of both equations

• Write both equations in standard form

write down the equation of the line if gradient = 2 y-intercept = -5

write down the equation of the line if gradient = 3/4 y-intercept = -1/2

What is the
slope-intercept form
of the equation
-8x+2y=4

• none

• y=2-4x

• y=4x+2

• y=4x-8y

Let's solve a system by GRAPHING. Put the steps in order from first to last.

• The intersection point is the solution

• Solve both equations for y to get slope-intercept form

• Graph both lines using the slope and y-intercept
