More guides on this topic.The gradient is the same all along the line, so it doesn’t really matter where you start or finish, but it is generally a good idea to use two points on the line that are far apart.Mar 13, 2018 · Because the x-value of the first point is zero, we can easily find a. 1.75 = ab 0 or a = 1.75. Plugging this value, along with those of the second point, into the general exponential equation produces 6.87 = 1.75b 100, which gives the value of b as the hundredth root of 6.87/1.75 or 3.93. So the equation becomes y = 1.75 (hundredth root of 3.93)x. To begin, we graph our first parabola by plotting points. Given a quadratic equation of the form y = ax2 + bx + c, x is the independent variable and y is the dependent variable. Choose some values for x and then determine the corresponding y -values.

The forms y=mx+b and y=mx+a are essentially the same, except for the naming of the constant term. The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m (x-a) is essentially different from the other two forms, and means slope m and x-intercept (instead of y-intercept) a. Sep 6, 2020 · Steps. Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11) Substitute the slope (m) in the slope-intercept form of the equation. Substitute either point into the equation. You can use either (3,5) or (6,11). Solve for b, which is the y-intercept of the line. Substitute b , into the equation. 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.
