Question

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

Answer 1

Answer:

Jaclyn did not make an error

Step-by-step explanation:

we know that

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

$m=\frac{y2-y1}{x2-x1}$

we have

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

Substitute the values

$m=\frac{0-4}{-3-0}$

$m=\frac{-4}{-3}$

$m=\frac{4}{3}$

therefore

Jaclyn did not make an error

Answer 2

Answer:

Jaclyn did not make error

Step-by-step explanation:

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

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

Step 2: Slope formula = $\frac{y_2 - y_1}{x_2 - x_1}$

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

Slope = $\frac{0 -4}{-3 - 0}$

Slope = $\frac{-4}{-3} = \frac{4}{3}$

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

So, Jaclyn didn't make a single error.
