The slope-intercept form of a line is: y=mx+b where m is the slope and b is the y-intercept.The y-intercept is always where the line intersects the y-axis, and will always appear as (0,b) in coordinate form.. In the first video, mathman1024 looks at the equation: y=32x−1 This equation is already in slope-intercept form, so we can tell that the slope is …

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. The slope of one line is the negative reciprocal of the other. We can show that two lines are perpendicular if the product of the two slopes is [latex]-1:{m}_{1}\cdot … how many watts is 2700 lumens
