Hey there!
<u>Solve </u><u>for </u><u>k </u><u>:</u>
k = -15 ✅
18 = -k + 3
<em>></em><em>></em><em> </em><em>Substrat </em><em>3</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>
18 - 3 = -k + 3 - 3
15 = -k
<em>></em><em>></em><em> </em><em>Dive</em><em> </em><em>each </em><em>side </em><em>by </em><em>-</em><em>1</em><em> </em><em>:</em>
15 / -1 = -k / -1
-15 = k
Therefore, your answer is k = -15

Have a good day :)
I think that the answer is B
I think you need to think about the problem carefully. My guess is 1,that's my guess. sorry i couldn't give an accurate answer or you divide 300 by 5
Given:
The equation of a line is
...(i)
The perpendicular line passes through the point (-1,4).
To find:
The equation of the perpendicular line.
Solution:
The slope intercept form of a line is:
...(ii)
Where, m is the slope and b is the y-intercept.
On comparing (i) and (ii), we get
Product of slopes of two perpendicular lines is -1.
Let the slope of perpendicular line is .
The slope of the perpendicular line is and it passes through the point (-1,4). So, the equation of the line is:
Add 4 on both sides.
Therefore, the equation of required line is .
The sum of the adjacent angles of a parallelogram is always equal to 180°.
So we know that
.
When we simplify that expression:
Isolate the y by divide both sides by 3:
