How would you graph y = 3x + 4 and -3x +y = 8
To graph y = 3x + 4, plot the y-intercept at (0, 4) and then use the slope of 3 (rise of 3 and run of 1) to plot another point, then draw a line through those two points.
To graph -3x + y = 8, first rewrite it in slope-intercept form, y = 3x + 8. Plot the y-intercept at (0, 8) and then use the slope of 3 (rise of 3 and run of 1) to plot another point and draw a line through those points.
To see both lines on the same graph, simply plot both lines on the same coordinate plane using the information provided above.
