Question

Write the equation of each line in slope-intercept form
(If possible, please show work)

Answer 1

Hey there! :)

Answer:

y = -2x + 13.

Explanation:

Plug in the slope and coordinates into the equation y = mx + b:

Where m = slope

x = x coordinate of point

y = y coordinate of point

3 = (-2)(5) + b

3 = -10 + b

3 + 10 = b

b = 13.

Now that the b value is found, rewrite the equation:

y = -2x + 13.

Answer 2

y = -2x + 13

Explanation:

Step 1: Write known variables

m = -2

y = -2x + b

Step 2: Find b

3 = -2(5) + b

3 = -10 + b

b = 13

Step 3: Rewrite equation

y = -2x + 13
