About what functions? You should take a photo of your work!
Answer:
We have: 2x+7y=−1
Let’s express this equation in terms of y:
⇒y=−27x−17
⇒ Gradient =−27
Parallel lines always have the same gradient:
⇒ Gradient of parallel lines =−27
Perpendicular lines have the negative reciprocal of the gradient:
⇒ Gradient of perpendicular lines =72

Answer:
(d) -0.253
Step-by-step explanation:
According to a z-score table for a standard normal distribution, a z-score of -0.25 corresponds to the 40.13th percentile, and a z-score of -0.26 corresponds to the 39.74th percentile.
Interpolating those values gives us the z-score for the 40th percentile. The 40.13th percentile is twice as close to the 40th percentile than the 39.74th, thus:

The answer is (d) -0.253.
Gradient is basically the same as slope in this instance. so the answer would be positive 4.
