Question

What is the equation of the line that passes through ( 1,5) and (4,11)?
Select one:
a. y = 6
b. y = x + 2
c. y = 2x + 3
d. y = 3x + 4

ANSWER PLEASE

Answer 1

wait

Answer 2

To find the slope:
(y-y)/(x-x)
=(11-5)/(4-1)
=6/3
=2

So you know so far that the equation is y=2x+__
Just plug in the x and y value of any of the points into the partially completed equation.
(5)=2(1)+3
or
(11)=2(4)+3

The equation is y=2x+3

Answer 3

ok
