Write an equation of the line in slope-intercept form and standard form

Given:

The graph of a line.

To find:

The equation of the line in slope-intercept form and standard form.

Solution:

From the given graph it is clear that the line passes through the points (0,-3) and (4,0). So, the slope of the line is:

The slope intercept form of a line is:

Where, m is the slope and b is the y-intercept.

The y-intercept of the given line is -3 and the slope is . So, the slope intercept form of the line is:

            ...(i)

Standard form of a line is:

Multiply both sides by 4 in (i).

Therefore, the slope intercept form of the line is and the standard form of the line is .

i believe that the answer is

b. y-1=-2(x-4)

hope this !
