Linear Equations

100

write in slope intercept form m=3 y-intercept= 5

y=3x+5

200

write in slope intercept form m= 1/5 y-intercept= -3

y=1/5x-3

300

write in slope intercept form m= 7 y-intercept= 8

y=7x+8

400

Identify the slope and y-intercept. y = 3 - 4x

What is slope is -4 and y-intercept 3?

500

Write the equation for a rise of 3 and run of 4. The line crosses the y-axis at -2. 

What is y = 3/4x -2

Mystery

100

what is the slope of (1,6) and (8,1)

-5/7

200

what is the slope of (2,7) and (-3,11)

4/-5

300

write in slope intercept form m= 3 y-intercept= -3

y=3x-3

400

solve for y 5x+y=4

y=-5x+4

500

solve for y: 6x+2y=8

-3x+4=y
