Also, in the slope intercept form, y=mx+b, m is equal to the slope. y2-y1/x2-x1 are the coordinates that you use to figure out the slope. B stands for the y-intercept. Y and x in the slope intercept form are only variables that you plug in from your points on the cortesian coordinate plane.
Contraction joint. c. Construction joint. Out of these Expansion joint and Contraction joints are stress relieving ones while the construction joint is not. Joints can be vertical or horizontal.
