Question

Find the equation of the line shown below.

A. y = –0.2x + 2

B. y = –5x + 2

C. y = 0.2x + 5

D. y = 5x + 2

Answer 1

A. y = –0.2x + 2

Explanation:

It is a negative slope and intersects at (0, 2).

Answer 2

Answer: A. y = –0.2x + 2

Explanation:

We see that the answer options are in slope-intercept form, so we will find the slope and the y-intercept of this line to write our equation.

The line intercepts the y-axis at (0, 2), so the ending of our equation will be "+ 2" for the intercept.

Next, we will find the slope. We see that for everyone one unit moved downward, there is 5 units right. This becomes a slope of -1/5, which is the same as -0.2.

Using these details, the correct answer is;

A. y = –0.2x + 2
