Two points of intersection are on the number at the coordinates (-1,2) and (4,-8).
Answer is 10(2k+5)
-----------------------------------
Work Shown:
20k+50 = 10*2k + 10*5
20k+50 = 10(2k+5)
Note how we can distribute the 10 back in to check our work
10(2k+5) = 10(2k)+10(5) = 20k+50
so that confirms we have the right answer
Another thing to notice is that 10 is the largest factor that we can pull out of 20k and 50. The value 10 is the GCF (greatest common factor) of 20 and 50.
Given:
The given equation of line is

To find:
The equation of line that passes through (-5,4) and is parallel to the given line.
Solution:
Slope intercept form of a line is
...(i)
where, m is slope and b is y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get

Slope of given line is
.
Slope of parallel lines are same. So, slope of parallel line is
.
The required line passes through (-5,4) with slope
. So, the equation of line is




Adding 4 on both sides, we get



Therefore, the correct option is a.
Answer:
Yes a number by itself is considered a constant.
