Question

What is the equation for the line that passes through the points (3, 4) and (5,8)?

Answer 1

y=2x-2

Explanation:

formula for the equation of a line is y=mx+b

formula for slope is (y2 - y1)/(x2-x1)

which makes the slope 2 (m=2)

then calculate for b which is -2

finally the formula is y = 2x - 2
