By putting the x and y values for the two points into the slope equation the value for m can be found. The equation of a line in the slope intercept form is. y = mx + b. After finding m using the slope equation substitute one set of point values for y and x. This leaves b as the only unknown. Slope the resulting equation for b.

The 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.Choose two points on the line. Any two points will work.

It is important to ensure we do not confuse the two-intercept form of the equation of a straight line with the standard form 𝑎 𝑥 + 𝑏 𝑦 = 𝑐. In the previous example, we had rearranged the equation of the line to give 2 𝑥 + 𝑦 = 6 at one stage in our working. This is not in two-intercept form as the constant on the right-hand side of the equation is not equal to 1. Recall that in the general slope-intercept equation y = m x + b , the slope is given by m and the y -intercept is given by b . Therefore, the slope of y = 2 x + 3 is 2 and the y -intercept is ( 0, 3) . In order to graph a line, we need two points on that line. We already know that ( 0, 3) is on the line. Additionally, because the slope of the ... ….

And what's our change in y here? So we went up from 4 to 7. We increased by 3. Our y decreased by 2. Change in y is equal to negative 2. So our slope, which is equal to change in y over change in x, is equal to negative 2/3. And if you wanted to relate that to the formulas that you normally see for slope, you're just looking at your end point. Since the resulting y-coordinate, f(0), is 5, we get that the y-intercept is given by the point (0, 5). Example Problem 2: Finding the y -Intercept of a Polynomial Function - Factored Form Find ...At this point, the x- coordinate is zero.
