Answer: The real answer is 19/10 or 1 and 9/10

Step-by-step explanation:

Jackie added 1/2 and 1/4 to get 1/8 but in order of operation you have to multiply and divide first . So she should have divided 1/2 by 1/4 and then added that with -1/10 .

<h2>Answer:</h2>

The Slope is \frac{2}{3}\\

<h2>Explanation:</h2>

Notice that both the points, (0,20) and (20,50), are on the line. So we can use those points to calculate the slope. Recall that that slope of the line m can be calculated by \frac{y_2 -y_1}{x_2 -x_1}\\ if we have the points, (x_1,y_1) and (x_2,y_2).

<h3>Calculating for the slope of the line:</h3>

Given:

(0,20)

(20,50)

m = \frac{50 -20}{20 -0} \\ m = \frac{30}{20} \\ m = \frac{2}{3}
