Basic Graphing Functions To find the Y-intercept of a graph that has been drawn: Press "2nd," then "TRACE" to go to the "CALCULATE" window. Highlight "value" and press "ENTER." At the bottom of the screen that appears, enter "0" after "X=." The result will be the Y-intercept and associated X-coordinate.

To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve for y.

To solve this, first find the equation of our line. The form of the question gives it to us very directly. We can use the slope-intercept form (y = mx + b). The x-intercept is found by setting y = 0, because that will give us the x-value at which the line crosses the x-axis.

Slope Intercept Form Formula: The slope intercept form of a line in the two-dimensional Cartesian coordinate plane is determined by the formula y=mx+b, y = m x + b , where m is the slope and b is the y -intercept.

X-intercept is the point where the line crosses the x-axis. Y-intercept is the point where the line crosses the y-axis. FINDING INTERCEPTS ALGEBRAICALLY: TO FIND THE X-INTERCEPT: LET Y = 0 AND SOLVE FOR X. TO FIND THE Y-INTERCEPT: LET X = 0 AND SOLVE FOR Y.

The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis. ... In the same way, the x-axis is also the line "y = 0". Then, algebraically, an x-intercept is a point on the graph where y is zero, and.

Lesson Summary Once again, the intercept form of a parabola is y = a (x - r)(x - s), where r and s are the x-intercepts, or where the graph passes through the x-axis. The benefit of using the intercept form is that you can easily find the x-intercepts without factoring or using the quadratic formula.

Using polynomial division, divide the numerator by the denominator to determine the line of the slant asymptote. To find x and y intercepts, set each variable equal to zero and solve in turn. Based on information gained so far, select x values and determine y values to create a chart of points to plot.

The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis. ... In the same way, the x-axis is also the line "y = 0". Then, algebraically, an x-intercept is a point on the graph where y is zero, and. a y-intercept is a point on the graph where x is zero.
