Question

Find the equation of the line that passes through points A and B

Answer 1

Answer: Equation: y = 2x - 1

Explanation:

Find the gradient

then use equation of a straight line

y = mx+C

m is gradient which is 2

plot either one of the 2 points and also the gradient in to find the C

7 = 2(4) + C

C = 7 - 8

C = 1

Equation: y = 2x - 1
