Answer:

y= $\frac{1}{2}x-2$

Step-by-step explanation:

Because of the slope, we would assume that it is 1/2 because when you use rise over run, the graph rises 1 unit up and shifts 2 units to the right. The -2 is where the y-intercept is (0, -2) based on the picture seen above. The slope is also positive where it is going up instead of going down.

iren2701 [21]

Answer:

Step 1

Step-by-step explanation:

Mark simplified 3/5 + 5/8 using the steps below:

Step 1: 3/5 * 8/5

Step 2: 3 * 8 / 5 * 5

Step 3: 24/5

Step 4: 4 4/5

Mark's error is in Step 1 where he changed the addition sign to multiplication sign.

The correct solution is:

$Step 1: \dfrac{3}{5}+ \dfrac{5}{8}\\Step 2: \dfrac{24+25}{40}\\Step 3: \dfrac{49}{40}\\Step 4: 1\dfrac{9}{40}$
