LINEAR EQUATIONS/GRAPHING

100

Identify the slope and y-intercept: 6x+3y=18

m=-2

b=6

200

Find the X-intercept and Y-intercept: -2x+5y=-20

x-intercept=10

y-intercept=-4

300

Solve for x: 

16x - 4 = 4(2x - 3)

x = -1.

400

Solve the proportion: b/8 = 9/4

b = 18

500

Explain in words how you would graph: y=-x+7

Plot the y-intercept - up 7 on the y-axis. Then go down 1, right 1 to plot another point. Continue this pattern until you can connect the points with a line.

WRITING, SOLVING AND GRAPHING LINEAR EQUATIONS
