A line passes through the points (-4, -16) and (0, 12). What is its equation in slope-intercept form?

Step-by-step explanation:

Goal

Write the equation of a line in slope-intercept form.

Given

Coordinate points which are (0,12) and (-4,-16).

Step 1

Find the slope by using slope formula or rise over run which is the changes of y over the changes of x

Substitute the coordinate points in the formula.

Step 2

Rewrite the equation by substituting the slope in slope-intercept form.

Substitute m = 7.

Step 3

Substitute any given coordinate points in the rewritten equation.

Substituting any given coordinate points will give the same solution.

Step 3.1

Substitute (0,12) in the equation.

Step 3.2

Substitute (-4,-16) in the equation.

Step 4

Rewrite the equation again by substituting the value of b.

Substitute b = 12.

Hence, the solution is y = 7x+12.

Hope this helps! Any questions about my answer can be asked in comments.

20000 as first it increases by 2500 then by 5000 so next it will increase by 10000
