Answer:
i dont know
Step-by-step explanation:
6
First you would do 6 minus 14 and end up with -8
Then you would do -8 times 3 which equals -24
Lastly you would do -24 divided by -4 and get 6
Therefore = -3.
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
