Understanding the Problem

To determine the intercepts of a line, we need to find the points where the line intersects the x-axis and the y-axis. The x-intercept is the point where the line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

The Given Equation

The given equation is:

yβˆ’4=7(xβˆ’6){ y - 4 = 7(x - 6) }

This is a linear equation in the slope-intercept form, where the slope is 7 and the y-intercept is 4.

Finding the X-Intercept

To find the x-intercept, we need to set y = 0 and solve for x.

0βˆ’4=7(xβˆ’6){ 0 - 4 = 7(x - 6) }

βˆ’4=7(xβˆ’6){ -4 = 7(x - 6) }

βˆ’4=7xβˆ’42{ -4 = 7x - 42 }

7x=38{ 7x = 38 }

x=387{ x = \frac{38}{7} }

So, the x-intercept is:

(387,0){ (\frac{38}{7}, 0) }

Finding the Y-Intercept

To find the y-intercept, we need to set x = 0 and solve for y.

yβˆ’4=7(0βˆ’6){ y - 4 = 7(0 - 6) }

yβˆ’4=βˆ’42{ y - 4 = -42 }

y=βˆ’42+4{ y = -42 + 4 }

y=βˆ’38{ y = -38 }

So, the y-intercept is:

(0,βˆ’38){ (0, -38) }

Conclusion

In this problem, we determined the x-intercept and the y-intercept of the line using the given equation. The x-intercept is the point where the line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. We found that the x-intercept is (\frac{38}{7}, 0) and the y-intercept is (0, -38).

    Determine the Intercepts of the Line: Q&A =====================================

Q: What are the intercepts of a line?

A: The intercepts of a line are the points where the line intersects the x-axis and the y-axis. The x-intercept is the point where the line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

Q: How do I find the x-intercept of a line?

A: To find the x-intercept, set y = 0 and solve for x. This will give you the point where the line crosses the x-axis.

Q: How do I find the y-intercept of a line?

A: To find the y-intercept, set x = 0 and solve for y. This will give you the point where the line crosses the y-axis.

Q: What is the equation of a line in slope-intercept form?

A: The equation of a line in slope-intercept form is:

y=mx+b{ y = mx + b }

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

Q: How do I determine the slope of a line?

A: To determine the slope of a line, you can use the formula:

m=y2βˆ’y1x2βˆ’x1{ m = \frac{y_2 - y_1}{x_2 - x_1} }

where (x1, y1) and (x2, y2) are two points on the line.

Q: What is the significance of the y-intercept in a linear equation?

A: The y-intercept is the point where the line crosses the y-axis. It represents the value of y when x is equal to 0.

Q: Can I have a linear equation with no x-intercept?

A: Yes, it is possible to have a linear equation with no x-intercept. This occurs when the slope of the line is zero, and the y-intercept is not zero.

Q: Can I have a linear equation with no y-intercept?

A: Yes, it is possible to have a linear equation with no y-intercept. This occurs when the slope of the line is not zero, and the y-intercept is zero.

Q: How do I graph a linear equation?

A: To graph a linear equation, you can use the slope-intercept form and plot the y-intercept. Then, use the slope to determine the direction and steepness of the line.

Q: What are some common mistakes to avoid when finding intercepts?

A: Some common mistakes to avoid when finding intercepts include:

  • Rounding answers
  • Incorrectly solving equations
  • Not checking work
