Question

Consider the system of equations. y = 3x + 2 and y = − 2 3 x − 4 Explain why these particular equations can be graphed immediately.

Answer 1

Y=2x+3 Y=2x+3 Y=2x+3

Answer 2

Sample Response: These equations are in slope-intercept form. I can use the y-intercept and slope to graph both lines. I plot the y-intercept and use rise over run to locate another point on the line. Then, I can draw a line through the two points.
