Indices Commodities Currencies StocksIn general, if the two points have the same y -value, the two points cannot be on the same parabola. Two points are not sufficient to specify a quadratic equation. Consider a quadratic equation in factored form. y=a (x-r_1) (x-r_2) If we specify r_1 and r_2, then we know exactly two points on this parabola, namely (r_1, 0), and (r_2, 0).

You can use this information to write the equation in slope-intercept form. To do so, you will need to follow several steps: Step 1: Begin by writing the formula for slope-intercept form: y=mx+b. Step 2: Substitute the given slope for m. Step 3: Use the ordered pair you are given (x,y) and substitute these values for the variables x and y in ...

So if we simplify this a little bit, we get 8 is equal to-- let's see, 5 times 17 is 50, plus 35 is 85-- is 85/13 plus b. Then to solve for b, we just subtract 85/13 from both sides. So we have 8 minus 85/13. 85/13 Is equal to b. And now we just have to subtract these two numbers. Use the slope that we found, together with ANY of the two given points. In this exercise, I will show you that we should arrive at the same value of the [latex]y[/latex]-intercept regardless of which point is selected for the calculation.

You would plug in 0 for x. So the equation would be 8*0 -2y =24, or -2y =24. Then you can solve it like a regular equation and you would get y =-12. For the x-intercept, it's basically the same thing, except you plug in 0 for y instead of x. So you would get 8x -2*0 =24 or 8x =24 ...

The method for finding the \(y\)-intercept of a quadratic function or the \(y\)-intercept of a parabola is the same as that of a line. If a quadratic equation is given, substitute \(x = 0\) and solve for \(y\) to get the \(y\) intercept. Finding the \(y\)-Intercept – Example 1: Find the \(y\)-intercept of the equation \(y=x^2-2x-3\). Solution:

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.
