Weby y -intercept and the slope using a straight edge (ruler) to reveal the graph of the line. Examples of Graphing a Line using the Slope and y y -intercept Example 1: Graph the line below using its slope and y y -intercept. Compare y = mx + b y = mx + b to the given equation \large {y = {3 \over 4}x - 2} y = 43x − 2 . WebFind the intercepts of the equation y = x 2 – 2x – 1. Step 1: Set x to 0 in your function to find the x-intercept: 0 2 – 2 (0) -1 = -1. Written as an ordered pair, the x-intercept is (0, -1). Step 2. Set y to 0 and then solve to find the y-intercept: 0 = x 2 – 2x -1 (setting y to zero) x = -1± √ 2 (using the quadratic formula to solve)
How to Use a Graphing Calculator to Find the X-intercepts
Weby-intercepts are when the line touches the y-axis. To find these, find the y when x = 0. The point for a y-intercept will look like (0,y) x-intercepts are when the line touches the x-axis. To find these, find the x when y = 0. The point for an x-intercept will look like (x,0) ( 4 votes) Samantha 6 years ago WebTo find the y-intercepts of a function, set the value of x to 0 and solve for y. What are the intercepts points of a function? The function intercepts points are the points at which … chilton jeep wrangler
