A line has a slope of negative 3/4 and goes through the point 0 comma 8. What is the equation of this line in slope-intercept form? So any line can be represented in slope-intercept form, is y is equal to mx plus b, where this m right over here, that is of the slope of the line. And this b over here, this is the y-intercept of the line. From $$A$$ and $$B$$ draw $$AL$$ and $$BN$$ perpendicular to the X-axis and from point $$P$$ draw $$PM$$ also perpendicular to the X-axis. Also from $$A$$ draw ... To find the equation of a line in a two-dimensional plane, we need to know a point that the line passes through as well as the slope. Similarly, in three-dimensional space, we can obtain the equation of a line if we know a point that the line passes through as well as the direction vector, which designates the direction of the line.

Determine the equation of a line passing through the points $(-2, 5)$ and $(4, -2)$. example 2: Find the slope - intercept form of a straight line passing through the points $\left( \frac{7}{2}, 4 \right)$ and $\left(\frac{1}{2}, 1 \right)$. To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y-intercept--this should be of the form (0, b). This set of equations is called the parametric form of the equation of a line. Notice as well that this is really nothing more than an extension of the parametric equations we’ve seen previously. The only difference is that we are now working in three dimensions instead of two dimensions.
