For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
While the point-slope equation of a line is given by:

Where:
m: It's the slope
It is a point through which the line passes
In this case we have a line through:
(8,4) and (0,2)
Therefore, its slope is:

Its point-slope equation is:

Then, we manipulate the expression to find the equation of the slope-intersection form:

Therefore, the cut-off point with the y-axis is 
ANswer:

Answer:
c., d., f
Step-by-step explanation:
"elana walked 12 miles"
That is 12.
"then she walked 1/4 that distance"
That is 1/4 of 12 miles, so it is 1/4 * 12
She walked altogether
12 + 1/4 * 12 = 12 + 3 = 15
She walked altogether 15 miles.
a.12+1/4 = 12.25 which is not 15
b.12×1/4 = 3 which is not 15
c.12+1/4×12 = 12 + 3 = 15 which is correct
d.12(1+ 1/4) = 12(1.25) = 15 which is correct
e.12×3/4 = 9 which is not 15
f.12×5/4 = 15 which is correct
Answer: c., d., f
