Graphing Linear Equations

100

John started graphing the equation, y=3/4x -1 by plotting a point at -1 on the x-axis. Was he correct?

No. It should be on the y-axis.

200

William attempted to graph the linear equation,          y = 1/2x - 5 by first plotting -5 on the y-axis, then going down 1 and over 2 (right) for the 2nd point. Was he correct?

No. He should have gone up 1 and over 2 (right).

300

Write y - 2 = 5(x + 3) in slope-intercept form.

y = 5x + 17

500

Juan graphed the linear equation, y = -2/3x + 5, by plotting the y-intercept (5), then going down 2 and over 3 (right) for his second point. He then drew a line through the two points. Is he correct?

Yes!

Writing a Linear Equation
