how to make a slope intercept equation. And so our equation is going to be y is equal to negative 23 x plus b. Y mx b where m is the slope of the line and b is the y-intercept of the line or the y-coordinate of the point at which the line crosses the y-axis.
All you need to know is the slope rate and the y-intercept. The slope intercept form is probably the most frequently used way to express equation of a line. 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.
12 is the y intercept b and -1 is the slope m and X is just there because its supposed to be.
Continue reading for a couple of examples. Find the y-intercept b. The equation and the line will change accordingly. It was changed to y -1x 12 so it will look like y mx b slope intercept form.
