Answer:
the y-intercept, b, is 7
Step-by-step explanation:
Compare the given y = -3.1 +7 to y = mx + b. I must assume that you meant
y = -3.1x +7. It becomes evident that the slope, m, is -3.1 and the y-intercept, b, is 7.

Answer:
2.3 units
Step-by-step explanation:
The unknown side is opposite the given angle 50 degrees, and the length of the hypotenuse is 3 units.
Since sin Ф = opp / hyp, we have here sin 50° = x/3, or x = 3 sin 50°.
Using a calculator, we find that the sine of 50° is 0.776.
Therefore, x = 3(0.766) = 2.298 units, or approximately 2.3 units
