Question

Can someone help me please. Will medal.
Screenshot of question will be in the comments.

Answer 1

First you need to calculate the vector between those 2 points. With that you can calculate the slope (m).
Then all you have to do is remembering that the equation for a slope is y = mx+b

All you have to do now is to put one of the points in the given equation to calculate the "b".

Answer 2

Any luck so far?

Answer 3

I have no idea how to do this.

Answer 4

Ok, so you have 2 points. E(-2,2) and F(5,1).
If you calculate the vector between them you'll get the slope. So:

Vector EF = F - E = (5-(-2), 1-2) = (7, -1)

Wich means the slope is -1/7

Now you have:

y = (-1/7)*x + b ; and you want to calculate "b"

So substitute the point (either E or F) in the formula above. Lets use F.

1 = (-1/7)*5 + b
1 = -5/7 +b
b = 1+5/7
b = 7/7 + 5/7
b = 12/7


So the answer is y = (-1/7)x +12/7

Answer 5

equation of the line passing through (x1, y1) = E( -2 ,2) and (x2, y2 ) = F(5, 1) is

\[y- y1 =\left( \frac{ y2- y1 }{ x2 -x1} \right) \left( x-x1) \right)\]

Answer 6

just plug in x1,yi,x2,y2 values and simplify it

Answer 7

Never mind i got it. Thank you tho.
