WebJun 26, 2024 · In order to find "b" (the y-intercept) from the equation y=mx+b ... If you know the slope (m), use any one of the given points by substituting the Y value of the given point for y, and substituting the X value of the given point for x. Solve for b = Y-mX. Upvote • 1 Downvote. Add comment. WebTo find the x-intercept we generally just use the same formula 'y=mx+b'. The reason that 'b' is the y-intercept is because at the 'y-axis, x=0'. By this I mean if you look at any graph, for the point a line touches the y-axis, the x-value of a coordinate is always = 0. Knowing this, if you substitute 0 in for x in the formula you get:
SOLUTION: how do you find the b in y=mx+b - Algebra
WebYou can plug any known point into the equation y = mx +b to find b. Using the point (x1,y1) that you used in finding m, you have \begin {equation} b = y_1 - mx_1 \end {equation} where m is ... Straight line is tangent to the curve. If line y = mx +1 is a tangent to F (x,y)= 0, where F (x,y) is a polynom of degree 2, then F (x,mx+1) = 0 have ... WebMay 7, 2024 · How do you find B values? So then, to get the b-value, which is the value of the y-intercept, you just grab your y = mx + b equation (dust it off if you haven’t used it in a while), and plug in the three value you’ve been given: those for x, y and m. Then you solve the equation for the one variable that’s left: b, the value of the y-intercept. do i need to pay ohio school district tax
