WebYou may already be familiar with the y=mx+b form (called the slope-intercept form of the equation of a line). It is the same equation, in a different form! The "b" value (called the y-intercept) is where the line crosses the y-axis. So point (x1, y1) is actually (0, b) and the equation becomes: Start with y − y1 = m (x − x1) WebThe equation of a horizontal line is y = b where b is the y-intercept . Since the slope of a horizontal line is 0, the general formula for the standard form equation, y = mx + b becomes y = 0x + b y = b. Also,since the line is horizontal, every point on that line has the exact same y value. This y-value is therefore also the y-intercept.
How do you solve for x in y=mx+b? Socratic
Webwhen you graph the line, mx+b=y and fill in the slope and y-intercept, the x and y represent points that are on the line that you graphed. For example, if the equation was 5x+10=y, … WebMay 10, 2024 · Just substitute them values in, rearrange to make b the subject which will give you the y-intercept ( b ). Explanation: For example: y = 2x + b and you know that the coordinate (5, 2) lies on this function. Simple substitute them in and work out your value of b. 2 = 2(5) +b b = 2 −10 b = − 8 Therefore your final equation will be: y = 2x −8 simpson predictions for 2023

The slope of the line, m, is found by. m = y2 −y1 x2 −x1. where (x1,y1) and (x2,y2) are the coordinates of any two points in the line. The y-intercept, b, is found by plugging in x = 0 into the equation, which results in y = b, and therefore is the y-intercept.
