(Q) Linear Equations, Graphs, and Slope

Hint:  Put each answer choice into slope-intercept form, solving for y.  Then put the equations in the calculator and observe the graphs.

• -3x + 3y + 16 =n 0
• 3x - 8y + 16 = 0
• -3x - 8y - 16 = 0
• 3x + 8y - 16 = 0

Hint:  Graph each of the answer choices.  Then just compare.

• II and IV
• I and III
• II and III
• I and IV

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
