13- A student finds the slope of the line between (9, 13) and (14, 17). She writes
What mistake did she
14 - 9
make?
a. She mixed up the x- and y-values.
b. She used y-values where she should have used x-values.
c. She did not keep the order of the points the same in numerator and the denominator.
d. She should have added the values, not subtracted them.

The answer is the option C. (she did not keep the order of the points the same in the numerator and the denominator). Hoping I helped. <3

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
