Understanding Linear Functions through Intercepts

What is the primary reason for finding the x and y intercepts when graphing a linear function?

• To determine the slope of the line

• To find two points that can be connected to form the line

• To calculate the area under the line

• To identify the midpoint of the line

When finding the x-intercept, what value is assigned to the y-coordinate?

• 7

• 1

• -7/2

• 0

What is the x-intercept of the line if the equation is solved to give x = -7/2?

• 3.5

• -7

• -3.5

• 7

How is the y-intercept determined in a linear equation?

• By finding the midpoint of the line

• By setting y to zero and solving for x

• By setting x to zero and solving for y

• By calculating the slope of the line

What are the coordinates of the y-intercept if y equals 7 when x is zero?

• (7, 0)

• (0, -7)

• (-7, 0)

• (0, 7)
