The points given are:

(4, 1) and (10, 6)

We can find the slope using the formula below:


\text{slope}=(y_2-y_1)/(x_2-x_1)

From the points given;

x₁=4 y₁=1 x₂ =10 y₂=6

substitute the values into the formula


\text{slope}=(6-1)/(10-4)
=(5)/(6)

To find whether the line rises or falls or is horizontal, let's find the equation of the line

substitute x₁=4 y₁=1 and m=5/6 into y=mx + b and find the intercept(b)

1=5/6 (4) + b

1= 10/3 + b

1-10/3 = b

-7/3 = b

substitute m=5/6 and b=-7/3 into y=mx + b, this gives the equation of the line.

That is;


y=(5)/(6)x-(7)/(3)

From, this, since the slope is positive, then the line rises
