As the general formular for a straight line is
m represents the gradient
c represents the point at which the line crosses the y axis.
Therefore you simply plug the numbers into the equation.
You can work out whether 2 lines are perpendicular by multiplying their gradients. The product of the gradient of perpendicular lines will always be -1.
If lines are perpendicular, M1× M2 = − 1
So you can rearrange the equation to get M2=-1/M1.
As they perpendicular they have to intercept at the same point on the Y axis therefore you get the equation
Answer:
27.55
Step-by-step explanation:
The mean of a set of numbers is the sum divided by the number of terms.
So 49.7 + 15.8 + 22.7 + 15.1 + 32.2 + 39.1 +27.7 + 18.1 = 220.4
220.4 / 8 = 27.55
I think the answer Is D fame
3.5g+12.2 is the simplified expression I believe
