Question

Write the equation for the line that passes through the points (4, 5) and
(6,9). *

Answer 1

y = 2x + 1

Explanation:

first find slops

(9-5)/(6-4) = 4/2 = 2 = m

y = mx + b

5 = 2(2) + b

1 = b

y = 2x + 1

Answer 2

y = 2x - 3

Explanation:

gradient of the line is

`(9 - 5)/(6 - 4 ) = 2`

equation will be:

`(y - 5)/( x - 4) = 2`

y - 5 = 2x - 8

y = 2x - 3
