(20pts) pls i need with my hw, pls show work

4. Just look at the graph, and see which coordinates are on the line.

D, E, and F are on the line.

5. The y-coordinate is (0,4), and the slope is (4 + 8)/(0 - 4) = -3. Therefore, the equation of the line is y = -3x + 4. Plugging in the numbers we know gives us b = -3*8 + 4. b = -20.

6. Find the number of times P is on a line. There are two lines that do so.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
