Question

Find the equation of the line that goes through the points (2, 10) and (-1, -2).

Answer 1

y=4x+1

Explanation:

Step 1: plot your points

Step 2: draw a line through them

Step 3: find the slope (RISE/RUN) = 12/3 = 4

Step 4: find the y-int = 1

y=mx+b where x and y are variables, m is the slope and b is the y-int

y = 4x + 1

Hope that helps
