put this equation in slope intercept form:

-4x + 2y = 8

• y = -2x + 8

• y = 1/2x + 8

• y = 2x + 4

• y = -1/2x + 4

If you were to graph this equation, where would your first point go? Then what would you do from that point?

y = -4x + 1

• First point on +1 on the y-axis, then go down 4 and over one

• First point on +4 on the y-axis and then go up 1 and over 1

• First point on +1 on the y-axis, then go up 4 and over 1

• First point on -4 on the y-axis, then go down 1 and over 1

What is the equation of this graph?

• y = -3/2x + 5

• y = 5x + 3

• y = -2/3x + 5

• y = 5x
