Graphing Equations in Standard Form

What is the purpose of finding x and y intercepts when graphing equations in standard form?

• To identify the midpoint of the line

• To calculate the area under the line

• To find the points where the line crosses the axes

• To determine the slope of the line

In the equation 4x - 5y = 20, what is the x-intercept?

• (0, 5)

• (-4, 0)

• (0, -4)

• (5, 0)

How do you find the y-intercept of the equation 4x - 5y = 20?

• Set both x and y to 0

• Set y to 0 and solve for x

• Multiply x and y by 5

• Set x to 0 and solve for y

For the equation -20x + 10y = 80, what is the x-intercept?

• (0, 8)

• (0, -4)

• (-4, 0)

• (8, 0)

What is the y-intercept of the equation -20x + 10y = 80?

• (-4, 0)

• (0, -4)

• (8, 0)

• (0, 8)
