Convert the standard form equation into slope-intercept form.
5x + y = -5

• y = -5x - 5
• y = ⅕x - 5
• x = ⅕
• y = 27, 239, 430

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

How would you graph y = 3/4x?

• Begin at the 3 then go up 4 and place a point

• Begin at (0,0) put a point Go up 4 right 3 put a point

• Begin at (0,0) put a point. Go up 3, right 4 put a point

• Begin at 4 put a point. Go up 3 right 1 put a point

Given that the slope is  2/3 and the y intercept is -3 what is the equation of the line?

• y = 2/3x - 3
• y = 2/3x + 3
• y = -2/3x - 3
• y = -2/3x + 3
