2.7: Interpreting the y-intercept of a Line - Mathematics LibreTexts

Weby = mx + b is the slope-intercept form of a staight line. In the equation y = mx + b for a straight line, m is called the slope of the line and b is the y-intercept of a line. y = mx+b, where y ⇒ how far up or down is the line, x ⇒ how far along is the line, b ⇒ the value of y when x = 0 and m ⇒ how steep the line is. WebSlope m = (y2-y1)/ (x2-x1) If you mulitply both sides by (x2-x1), then you get point slope form: (y2-y1) = m (x2-x1) Then, they swab a couple of variables to clarify the variables that stay. X2 becomes X, and Y2 becomes Y. And, you have the point slope form. Remember, slope is calculated as the change in Y over the change in X. WebAll of the lines shown in the graph are parallel because they have the same slope and different y-intercepts.. Lines that are perpendicular intersect to form a [latex]{90}^{\circ }[/latex] angle.
