Question

What is the equation of the line which includes points (2,3) and (0,10)?

Answer 1

ok so first step in the equation is to use point-slope form. Also known as (y2-y1)/(x2-x1).
So its: 10-3/0-2= -7/2
next you choose one of the two sets of points to plug in as (x,y)
10=-7/2(0)+b
10= 0+b
b= 10
now we have your y intercept.
So your equation is y=-7/2x+10

Answer 2

(2,3) and (0,10)
The equation would be of the form
y = mx + b
First we must calculate the slope.
which can be determined by:
m= 10 -3 / 0 -2
m = 7/-2

Answer 3

Okay.

Answer 4

So after calculating the slope, what's next?

Answer 5

next you choose one of the two sets of points to plug in as (x,y)
10=-7/2(0)+b
10= 0+b
b= 10
now we have your y intercept.

Answer 6

i used (0,10)

Answer 7

So after the Y intercept is found, I have to calculate the other one?

Answer 8

nope. after you find your y-intercept your done. your equation is: y= -7/2x+10

Answer 9

Oh. Thank you.

Answer 10

anytime :)

Answer 11

Thank you both for your help.
