WebDec 9, 2024 · Use the equation of the function to find the y- intercept. y = 12 x2 + 48 x + 49 The y-intercept has two parts: the x-value and the y-value. Note that the x-value is always zero. So, plug in zero for x and solve for y: y = 12 (0) 2 + 48 (0) + 49 (Replace x with 0.) y = 12 * 0 + 0 + 49 (simplify) y = 0 + 0 + 49 (simplify) y = 49 (simplify) WebTo find the intercepts: When you want the x intercepts (x,0): Set y=0 then solve for x When you want the y intercepts (0,y): Set x=0 then solve for y Example: Find the intercepts of y = x 2 − 4 x intercept: set y=0 0 = x 2 − 4 x 2 = 4 x = 2 or −2 The points are (2,0) and (−2,0) y intercept: set x=0 y = 0 2 − 4 y = −4 The point is (0,-4)
What is the Y-Intercept? (Sample Questions) - Mometrix
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 … WebJan 3, 2016 · How to find the x-intercept and y-intercept for a linear equation in standard form (Ax + By = C) or slope-intercept form (y = mx + b). bitcoin core 23 lightning network windows
Equation of a Straight Line - mathsisfun.com
WebThe equation of a straight line is usually written this way: y = mx + b (or "y = mx + c" in the UK see below) What does it stand for? y = how far up x = how far along m = Slope or Gradient (how steep the line is) b = value of y when x=0 How do you find "m" and "b"? b is easy: just see where the line crosses the Y axis. WebTo solve for the y-intercept, set the x value equal to zero: Report an Error Example Question #4 : How To Find X Or Y Intercept What is the x-intercept of ? Possible Answers: Correct answer: Explanation: To solve for the x-intercept, set the y value equal to zero: Subtract from both sides: Report an Error WebJun 3, 2024 · 1. Pick two points on the line. Draw dots on the graph to represent these points, and note their coordinates. Remember when graphing points to list the x-coordinate first, then the y-coordinate. For example, you might choose the points (-3, -2) and (5, 4). 2. Determine the rise between the two points. daryl fairweather twitter
