Answer:
Therefore = -3.
Step-by-step explanation:
i) let us say the slope of the line passing through (-2,7) and (4,9) is .
ii) to find the slope of the line passing through two points (,
) and (
,
) we use the formula m =
. Therefore we can say that
=
=
.
iii) let us say the slope of the perpendicular line to the line passing through (-2,7) and (4,9) is
iv) from the formula for the slopes of a line and the line perpendicular to it which is given by ×
= -1, therefore
= -1 ÷
= -3. Therefore
= -3
Answer:
You have to solve for the letter
