When the line is graphed m is the slope of the line and b is where the line crosses the y-axis or the y-intercept.
. Follow along with these examples to see how to translate linear functions into a graph. Draw your line using the two points you plotted y-intercept b first slope m second. The slope intercept form is probably the most frequently used way to express equation of a line. Plug the slope and the x and y of one of the given points into y mx b then.
This way is called the Slope-Intercept Form. And when you write something in slop-intercept form where you explicitly solve for y y is equal to some constant times x to the first power plus some other constant the second one is going to be your intercept your y-intercept or its going to be a way to figure out the y-intercept the intercept itself is this point the point at which. The formula for a line in slope-intercept form is y mx b where x and y are coordinates on a graph m is the slop and b is the y-intercept. B 2 5.
