Hello there!
To solve this question, let's figure out a ratio of how much an x variable goes up by how much the y goes up. If it is a linear function (meaning a straight line), this ratio should stay consistent throughout the whole data plot.
For the first one, we can see that x is going up by 1, and so is y. But on the second to last, it jumps up once on the x value by 1, but y went up by two. This is not a consistent ratio and is considered nonlinear.
For the second one, we can see that for every x value going up 1, the y goes up by 1 too, as seen between the transition from the x values 1 to 2. However, when it goes from 2 to 4, the correct y value, if linear, should be 5.8. This is nonlinear.
The last one says that when x goes up by one, y value decreases by 2. this stays consistent all around and is linear.
(3,0)(0,4)
slope = (4 - 0) / (0 - 3) = -4/3
A perpendicular line will have a negative reciprocal slope. So our perpendicular line has a slope of 3/4
y = mx + b
slope(m) = 3/4
(-6,-5)....x = -6 and y = -5
now sub into the formula and find b, the y int
-5 = 3/4(-6) + b
-5 = -18/4 + b
-5 + 18/4 = b
-20/4 + 18/4 = b
-2/4 = b
so ur perpendicular line is : y = 3/4x - 2/4....or 3x - 4y = 2
and ur point (6,4) lies on the perpendicular line <===
Answer:
$1165.73
Step-by-step explanation:
We have 395.95+159.95+750+129.95=1435.85. Once we have this, we add the student discount of -25%. This rounds to 358.96. We subtract this from the total and get 1076.89. After the student discount, we add the sales tax of 8.25%. This adds a total of 88.84 to the final amount. After adding this we get a final total of $1165.73
The correct answer is a,c,d
