Answer:
Slope is -3/7. Y intercept is 250/7.
Step-by-step explanation:
Since they asking for the slope and y intercept, let put it in slope intercept form.
where m is the slope and b is the y intercept.
The equation given is in standard form so we will convert it to slope intercept.
The slope is -3/7
The y intercept is 250/7
Answer:
150 degrees
Step-by-step explanation:
Graphing the complex number we see the angle terminates in the second quadrant. This means the argument, the angle, will be between 90 degrees and 180 degrees.
So if we create a right triangle with that point after graphing it. We see the height of that triangle is 5 because that is the imaginary part. The base of that triangle has length . The problem is this doesn't give us any part of the angle we want, but it does give us the complementary of the part of the angle that is in second quadrant.
Let's find the complementary angle.
So the opposite side of the complementary angle is 5.
The adjacent side of the complementary angle is .
So 90-30=60.
The answer therefore 60+90=150.
