Answer to Mathematics Knowledge Question on Y-Intercept
Mathematics Knowledge
Yesterday I presented a question on y-intercept. Do you know the y-intercept of the line y = x?
Angles and slope is one of the 15 subtopics that I review for the Mathematics Knowledge as an ASVAB tutor. The standard slope-intercept form of a line is y = mx + b. M is the slope or steepness of the line. M is the value that comes before x. B is the y-intercept, the point where the line crosses the y-axis.
In the line y = x, there is no number before x, so the number is 1. That means the slope is 1. There is nothing be added or subtracted from x, so the y-intercept is 0. Did you know that the y-intercept of this line is 0?
