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

the discriminant is 64 + 4*1*12 = 112

this is prime.
