WebJul 24, 2024 · Find an Equation of the Line Given the Slope and y -Intercept. We can easily determine the slope and intercept of a line if the equation was written in slope–intercept form, y=mx+b. Now, we will do the reverse—we will start with the slope and y -intercept and use them to find the equation of the line. Exercise 3.6.1. WebExample: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line When x increases, y increases twice as fast, so we need 2x When x is 0, y is already 1. So +1 is also needed And so: y = 2x + 1 Here are some example values: Check for yourself that those points are part of the line above! Different Forms

WebTo write the equation of a line, first find the slope. Remember that slope is the change in y over the change in x. To find slope, find two points on the line. Then use either the slope formula (y2-y1)/(x2-x1) or use the slope triangle. To use a slope triangle, connect the two points by drawing a triangle. WebFinal answer. Transcribed image text: 2.

WebApr 16, 2024 · Finding the equation of a line can be accomplished in a number of ways, the first of which makes use of slope-intercept form, y = mx + b. If we know the slope, m, and the y -intercept, (0, b), we can construct the equation. Example 4.5.1 Find the equation of a line with slope m = − 5 8 and y -intercept (0, 1). Solution: WebJun 29, 2024 · It is y=mx+c where: [1] y is the number in relation to the y-axis; m is the gradient or slope of the line; x is the number in relation to … WebPlot the x and y-intercepts and draw the line on the graph paper!
