Using distance formula, I got C.
Answer:
The line will be going 'uphill' from left to right
Step-by-step explanation:
we know that
The equation of the line into slope intercept form is equal to
y=mx+b
where m is the slope
b is the y-intercept
If the coefficient of the x-term is positive
then
the slope is positive
therefore
If the values of x increases, the values of y increases
If the values of x decreases, the values of y decreases
The line will be going 'uphill' from left to right
