Pre Algebra Graphing Slope Intercept and Standard Form

What is the slope of the line 5x-10y=21

• -5/10

• -10/5

• 1/2

• -2

which graph represents the equation y=2x

• 
• 
• 
• 

• y=2x+4

• y=-2x-4

• y=2x-2

• y=2x-4

When converting the equation

2x + 4y = 8

into slope-intercept form, the first step to solve for y would be to ____________.

• subtract 2x from each side

• subtract 4y from each side

• add 2x to each side

• add 4y to each side

When converting the equation 2x - 3y = -9 into slope-intercept form, the first step to solve for y would be to ____________.

• subtract 2x from each side

• subtract 3y from each side

• add 2x to each side

• add 3y to each side

When converting the equation -x + 2y = -10 into slope-intercept form, the first step to solve for y would be to ____________.

• add x to each side

• subtract x from each side

• add 2y to each side

• subtract 2y from each side

3x + y = 12

• y = -3x +12

• x = y + 4

• x = y + 12

• y = 3x -12

x + y = 4

• y = x + 4

• y = -x + 4

• x = -y + 4

• x= y - 4

Solve for y
5x + y = -10

• y = 5x + 10

• y = -5x - 10

• y=-3x+1

• y=3x+1

• y=1/3x+1

• y=-1/3x-1
