WebTo find the xintercept we generally just use the same formula 'y=mxb' The reason that 'b' is the yintercept is because at the 'yaxis, x=0' By this I mean if you look at any graph, forWebyintercept = −3 xintercept = −38 Explanation Convert the formula into the standard form of y = mx c 4x8y = 17 http//wwwtigeralgebracom/drill/4x_8y=17/ 4x8y=17 GeometricWebThis form of the equation is very useful The coefficient of "x" (the "m" value) is the slope of the line And, the constant (the "b" value) is the yintercept at (0, b) So, if you are given an
