How do you find the x intercept of the graph of an equation?

To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. For example, lets find the intercepts of the equation y = 3 x − 1 \displaystyle y=3x – 1 y=3x−1. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

How do you solve 2x 4y 9?

  1. 2x-4y=9. 2x−4y=9. Subtract 2x from both sides. Subtract 2x from both sides.
  2. -4y=9-2x. −4y=9−2x. Divide both sides by -4. Divide both sides by −4.
  3. \frac{-4y}{-4}=\frac{9-2x}{-4} −4−4y​=−49−2x​ Dividing by -4 undoes the multiplication by -4.
  4. y=\frac{9-2x}{-4} y=−49−2x​ Divide 9-2x by -4.

How do you find the X intercept when given two points?

Approach:

  1. Find the slope using the given points.
  2. Put the value of the slope in the expression of the line i.e. y = mx + c.
  3. Now find the value of c using the values of any of the given points in the equation y = mx + c.
  4. To find the x-intercept, put y = 0 in y = mx + c.
  5. To find the y-intercept, put x = 0 in y = mx + c.

How do you find the x intercept in slope form?

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.

Where are the x intercepts?

The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

What is x-intercept form?

A linear equation has the form y = mx + b, where M and B are constants. The x-intercept is the point where the line crosses the x-axis. By definition, the y-value of a linear equation when it crosses the x-axis will always be 0, since the x-axis is stationed at y = 0 on a graph.
