~= 2x+~ 4 4 Y = 2x+ 2 tJJ

Right!

2x+ 4y = 8 2x- 2x+ 4y = -2x+ 8

4y = -2x+ 8

Remember------------------------------,

Putting an equation in slope-intercept form makes it easier to understand and graph. In the equation y = mx + b, m is the slope of the line and b is the y-intercept.

Solve for y to rewrite each equation in y = form. Shade in your answers below to reveal a message. You need to also write the equation on answer blank on the graph paper, and use your graphing calculator to help you graph the linear equation.

1. 4x + 2y = 10 y= 7. 7y 14x = -28 y= j

2. 5y - 25x = 10 y= 8. 3y - x = 12 y=

3. x - Y = 1 y= 9. -5x - Y = -1 y=

4. 3y - 12x = 6 y= 10. X + 4y = 36 y=

5. 4y + 4x = -4 y= 11. 3y - 2x = -9 y=
