Graphing Systems of Equations by Substitution and Graphing

What does "m" represent in y=mx+b?

• y-intercept
• slope
• macaroni
• nothing

Which represents slope in y=4x+3

• 3
• 4x
• 4
• x

How would you write the equation with a slope of 2/3 and a y-intercept of -3

• y=3/2x+3
• y=2/3-3
• y=2/3x-3

If m = 1/2 and b = -4, what is the correct slope-intercept equation?

• y=1/2x+4
• y=1/2x-4
• y=1/2-4
• y=4x+1/2

Find the slope of the line.

• -5/4
• 5/4
• -4/5
• 4/5

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

what is the slope intercept form for the equation -2x + 8y = 2

• y = -2x + 8

• y = 1/4x + 1/4

• y = -1/4x - 1/4x

• y = 2/8x + 4
