Linear Equations

100

Write an equation in slope-intercept form for a line with a slope of 3 and a y-intercept of -2. 

y= 3x-2

200

In the following equation which number is the slope?

y=1/2x + 4

The slope is 1/2

300

In the following equation, which number is the y intercept?

y=8x -10

The y intercept is -10

400

Find the slope (9,10)(12, 11)

The slope is 1/3

500

The equation y = mx + b represents a line. What do the m and b stand for?

The m stands for slope, the b stands for the y intercept 

Equations

100

Solve the following equation:

x + 12=25

x=13

200

What would be the first step to solving this equation?

-10x + 25 = 35

The first step would be to move the 25 by doing the opposite, -25 to both sides.

300

Solve for x:

2x + 8 = 4x -12

x=10

400

Tell what the first step would be in solving this problem:

4(x+2)=24

Distribute the 4 to the numbers inside of the parenthesis. 

500

4(x-5)+2=4x-18

Infinitely many solutions
