Question

Jaclyn used the slope formula to find the slope of the line in which step did Jaclyn make an error?

through the points given in the table.
In step 1, she switched the x and y values in point
2
In step 2, she used the wrong formula for slope
In step 3, she simplified the slope incorrectly
Jaclyn did not make an error
1. Point 1: (0,4); Point 2: (-3,0)
2. Slope V2 -6 - 4
3. Slope = 3

Answer 1

Jaclyn did not make error

Explanation:

Step 1: He has taken two points from the given table.

(0, 4) and (-3, 0)

Step 2: Slope formula =
`(y_2 - y_1)/(x_2 - x_1)`

Step 3: Now plug in
`x_1 = 0, y_1 = 4, x_2 = -3 and y_2 = 0` in the above formula.

Slope =
`(0 -4)/(-3 - 0)`

Slope =
`(-4)/(-3) = (4)/(3)`

When we divide two negative numbers, the result will be in positive.

So, Jaclyn didn't make a single error.

Answer 2

Jaclyn did not make an error

Explanation:

we know that

The formula to calculate the slope between two points is equal to

`m=(y2-y1)/(x2-x1)`

we have

`(0,4)\ B(-3,0)`

Substitute the values

`m=(0-4)/(-3-0)`

`m=(-4)/(-3)`

`m=(4)/(3)`

therefore

Jaclyn did not make an error
