A line passes through points (0, k) and (4,0) and has a slope of –2.5. Which statements are true regarding the graph of the line?

Given the line that passes through points (0, k) and (4,0) and has a slope of –2.5, we need to get the value of "k

The formula for calculating the slope of a line is expressed as:

Hence the value of k is 10.

From the coordinate given (0, 10) and (4, 0), we can see that the y intercept and x intercept of the graph is 10 and 4 respectively

A. The equation of the line is y=−2.5x+10.

C. The y-intercept is k.

F. The value of k is 10.

Step-by-step explanation:

A line passes through points (0, k) and (4,0) and has a slope of –2.5. Which statements are true regarding the graph of the line?

A. The equation of the line is y=−2.5x+10.

B. The equation of the line is y=−2.5x.

C. The y-intercept is k.

D. The y-intercept is 4.

E. The value of k is 4.

F. The value of k is 10.

Solution:

The slope of a line is the ratio of the vertical change to the horizontal change. The slope (m) of a line passing through is:

Given that the line passes through (0, k) and (4,0)

The equation of the line is given as:

The y intercept is the value of y when x = 0, hence intercept = k

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
