WebJul 22, 2016 · Explanation: 2x + y = -8 is the equation of a line. When this line crosses the x-axis the value of the y-coordinate will be zero. Substituting y = 0 into the equation and solving for x gives the x-intercept. 2x +0 = −8 ⇒ 2x = −8 ⇒ x = −4. ⇒ x = − 4 is the x-intercept. Similarly, when the line crosses the y-axis the value of the x ... WebPurplemath. In the equation of a straight line (when the equation is written as " y = mx + b "), the slope is the number " m " that is multiplied on the x, and " b " is the y - intercept (that is, the point where the line crosses the vertical y -axis). This useful form of the line equation is sensibly named the "slope-intercept form".
WebHere are the steps to find the y intercept of a function y = f (x), we just substitute x = 0 in it. solve for y. represent the y-intercept as the point (0, y). Here are some examples of y … WebRewrite the equation 4x – 2y = 12 in slope-intercept form. 4x – 2y = 12 -4x -4x 1. Subtract 4x from each side to isolate y. -2y = -4x + 12 2. Simplify. -2 -2 -2 3. Divide each term by -2 to get y by itself. y = 2x - 6 4. Simplify. Rewrite each of the following equations in y = mx + b form. Show each step!
WebMay 17, 2024 · To find the y-intercept from a quadratic equation, substitute 0 as the value for x and solve. The y-intercept is always equal to the value of c in the equation. Example: Find the y-intercept in the quadratic equation y = 2 x 2 + 3 x + 4. y =. 2 (0)2 + 3 (0) + 4. First, rewrite the equation by substituting 0 for x.
