The combination of the INTERCEPT and SLOPE functions will give us the ordinate and the abscissa of the intersection point between two lines. The INTERCEPT function will estimate the distance of the intersection of the lines on the y-axis. Send us Feedback. Free y=mx+b calculator - find the slope intercept form of a line given two points, a function or the intercept step-by-step. waterboy5281, I suppose you are right, that there is typically a trade-off between efficiency and precision, given the same algorithm. However, a better algorithm is often both faster and more precise. @mcdowella, I like the idea of finding the approximate position of the intersection via the "nearest data point" method, and then using this information to …The y intercept of ANY two variable function is found by setting x = 0. We have the function. q(x) = − 7x−4 −1. So we set x=0. yint = q(0) = −70−4 − 1. = − 7−4 −1. flipping the negative exponent upside down we have. = − 1 74 − 1. Now we just play with the fractions to get the correct answer..
