X-intercept and y-intercept - GED Math

The equation in which when is graphed by a line that includes point - that is, its -intercept is 9. Therefore, substitute 0 for in each equation and solve for .

The correct choice is , since is a solution of this equation.

To find the , we need to set equal to 0 in our equation:

Now solve for :

To find the , we need to set equal to 0 in our equation:

Now solve for :

To find the , set the equal to 0:

Then solve for :

To find the , set the equal to 0:

Then solve for :

To find the , set equal to 0:

Then solve:

Remember, the square root of is both and

To find the, set equal to 0:

Then solve:

The x-intercept is the value of when .

Substitute the value into the equation and solve for .

Subtract 6 on both sides.

Divide by 3 on both sides.

The answer is:

The y-intercept is the value of when .

Substitute zero for x.

Subtract 1 on both sides.

Divide by 4 on both sides.

The answer is:

To find the y-intercept, we will look at the slope-intercept form of a line:

where m is the slope and b is the y-intercept.

So, given the equation

we can see the y-intercept is -11. Note that we must include the negative sign.

The y-intercept is the value of when .

Substitute into the equation.

Divide by 2 on both sides.

The answer is:

We can obtain two known points from using the intercepts. The y-intercept is when , and x-intercept is when .

The points are:

Write the formula for the slope.

The answer is:

The x-intercept is the value of when .

Substitute into the given equation.

Add 6 on both sides.

Divide by 5 on both sides.

The answer is:

The x-intercept is the value of when . Substitute the value for y.

Add one on both sides.

Divide by three on both sides.

The answer is:

The following equation is already written in slope-intercept form.

The y-intercept is the variable .

Since the value is absent, the y-intercept is zero.

The answer is:

Recall that at the x-intercept, the y-coordinate will be . Thus, plug in for in the given equation.

The coordinates of the x-intercept is located at .

Start by finding the slope of the line by using any two points.

Recall how to find the slope of a line:

Using the points , we can find the slope.

Now, we can write the following equation:

To find the value of , the y-intercept, plug in any point into the equation above. Using the point , we can write the following equation:

Thus, the complete equation for this line is .

Find the x-intercept of the following equation:

The x-intercept is the point where the line crosses the x-axis. At this point, the y-value must be 0.

To find the x-intercept, plug in "0" for y and solve for x.

Now finish up by dividing by 2:

We can check our answer by plugging it back into our equation:

Everything looks good, so our answer is -8.5

Find the x intercept of the following linear equation.

x intercepts occur when y=0, in other words, when we have no height.

So, plug in 0 for y and solve for x

So our x intercept is negative one half.

Find the y intercept of the following linear equation.

The y-intercept occurs when x is 0. Find it by plugging in 0 for x and solving for y.

So our answer is 1.5
