A student used the slope-intersept form to write the equation of a line that has a slope of -2 and passes through the point (-3/10, 5). The students work is shown on the left. One of the pickures has the answers.

D. Step 6: student needed to add the b value

Explanation:

All the steps are correct and they get the b value of 4.4. Since it's positive, it should be added in the orignal equation. So, it should look like y = -2x + 4.4 instead of y = -2x - 4.4

there is no picture

step-by-step explanation:

put up a picture so people can you

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
