y = 3x + 2. y = 4x - 9. We must find a point (x,y) that satisfies both linear expressions. To find such a point, we must solve the linear equation: 3x + 2 = 4x - 9. To do this, we must write the variable x to one side, and all terms without x to the other side. So the first step is to subtract 4x on both sides of the equal sign. 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 ... This is found by setting the x-value to zero in the function and solving for y. The standard form of a quadratic function is y = a x 2 + b x + c, where the y-intercept is the value of ( c ). To put this into practice, suppose we have a quadratic function f ( x) = 2 x 2 + 3 x + 1. To find the y-intercept, I evaluate the function when ( x = 0 ). 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. If you are given two points on the line, then you first need to find the slope of the line and then use the Point-Slope Equation and ONE of the given points to ...

Step 1: Find the slope (m). Use the formula to find the slope between the two points. Once you know the slope, plug it in for m in y = mx + b. This gives you y = 3x + b. Step 2: Find the y-intercept (b). Pick one of the points on the line and use the x and y values to find b. It does not matter which point you choose.

It is the point where the line …For a quadratic function, a graph can intercept the x-axis in at most two distinct points. When the graph of a parabola crosses the x-axis, such points are said to be the x-intercepts of the parabola.Finding the y-intercept of a parabola can be tricky. Although the y-intercept is hidden, it does exist. Use the equation of the function to find the y-intercept. y = 12x 2 + 48x + 49 The y-intercept has two parts: the x-value and the y-value. Note that the x-value is always zero. So, plug in zero for x and solve for y:A vertex is a corner, where two lines meet. A straight line by itself doesn't have a vertex. The easiest way to find the x intercept is to figure out what value x will have when y = 0. So if you have an equation of a line: 2y + 4x = 28. you substitue "0" in for your y and solve: 2 (0) + 4x = 28. 4x = 28.Therefore it you want to plug in 0 for your x values. y = ax2 + bx + c, has a y-intercept at c. If given a graph: the y-intercept passes through y-axis. Example: If a graph passes the y-axis at -1, then the y-intercept is -1.
