3. Slope-Intercept Form Method: Slope-intercept form (y = mx+b) allows us to graph linear equations easily by identifying the slope (m) and y-intercept (b). Start by plotting the y-intercept on the ...

To graph a linear function: 1. Find 2 points which satisfy the equation. 2. Plot them. 3. Connect the points with a straight line. Example: y = 25 + 5x. let x = 1 then y = 25 + 5(1) = 30. let x = 3 ...
