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.
