The slope of that equation is (1/3)x. To find the perpendicular slope of a slope, you would have to find the reciprocal. To do this:
Flip the slope, and add a negative. It'll equal to -3x. Visual representation:

now the perpendicular slope is -3, you will need to put this into point slope form, which is y - y1 = m(x - x1)
x1 = 5, y1 = -3
It'll equal to: y + 3 = -3(x - 5)
Now, you need to convert this to slope intercept form y = mx + b. All you need to do is just to distribute the -3 in that binomial, and move that 3 in the left side to the right side. It is easy!
Follow the representation, and there you go!

It's 96%
816/850 = 0.96, which is 96%
Hope I helped! ( Smiles )
Step-by-step explanation:
500 ×1.07^t <-- function (I think)
500 × 1 07^2 = $572.45 <-- balance after 2 years
In the form y = mx + c
First thing's first, we can determine the gradient, m, simply by looking at the points.
The gradient is determined by how much the value of y increments (or decrements) for each increase of 1 on the x axis.
Every time x increases by 1, y decreases by 4, meaning our gradient is -4.
We are also able to determine our constant, c, by seeing where our line will cross the y axis. In this case, there is a point dead-on the y axis at (0, -2), meaning our constant is -2.
With this information, we can put together the linear equation, y = -4x -2.
First You do length times width which would be 54 and then divide that by 3 and you would get your answer.
54÷(9×6)
