Question

The pair of points (6,y) and (10, -1) lies on a line with a slope of 1/4. What's the value of y?

a. -5
b. -2
c. 2
d. 5

Answer 1

Use the set of coordinates (10,-1) & the value for gradient 1/4 to find equation of the line in the form of y=mx+c .

Once you have the equation, sub in the x-value of 6 and solve for y.
That will give you the answer to your question

Answer 2

i know I probably sound unappreciative but do you know the answer?? @harman.singh

Answer 3

I do know how to find the answer but I think its better if you do it. You can ask me as many times you like if you get stuck.

Here is more information:
\[y-y _{1}=m(x-x_{1})\]
\[y+1=m(x-10)\]
Can you try finding the equation from here?

Answer 4

What is m stand for?

Answer 5

m stands for the gradient or the slope. It is given to you in the question (1/4)

Answer 6

So you can sub in m=1/4 into the equation

y+1=m(x−10)

y+1=1/4(x-10) and continue from there..
