Question

Write the equation of the line that passes through the points (3,6) and (5, 18) using function notation.

Answer 1

Y = 6X - 12

Explanation:

Given points through which line is passing as

X1 = 3 X2 = 5

Y1 = 6 Y2 = 18

Now equation of line is written as

Y-y1 = m (X-x1) m=
`(y2-y1)/(x2-x1)`

m =
`(18-6)/(5-3)`

m =
`(12)/(2)`

or m = 6

so the equation can be written as Y- 6 = 6 (X-3)

Y - 6 = 6X - 18

Y = 6X - 12 Answer
