Answer:
B.17 °
Step-by-step explanation:
note : can uh be more specific to the question it seems incomplete
If you are trying to find the y intercept then you have already found it, it is 4. From that point you would then draw the rest of the slope.
Instead of drawing from (0,0) you would go up 4 units and then do rise over run (7/3) to plot your line.
First use distributive property on both sides of the equation.
-9(-16 - f) = 4(1 - 3f)
144 + 9f = 4 - 12f
Then isolate f on one side of the equation:
3f = -140
f = 46.67 --> (which is equal to -140/3)
I'm sorry I couldn't help more. I don't know why it's wrong. Maybe try putting in it decial form instead.
