Name Slope-Intercept Form Wrong! 2x+ 4y = 8 2x+ 4y = 8 2x- 2x+ 4y = -2x+ 8 4y = 2x+ 8 4y = -2x+ 8 \ \I ~= 2x+~ tJJ 4 4 Y = 2x+ 2 -2x 8 = + 4 4 x+2 Y = --.1 2 ~ 4 Right! 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. 14x = -28 1. 4x + 2y = 10 y= 7. 7y 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.
