Write an equation of a line in slope-intercept form for the given conditions.
-intercept and -intercept
(Hint: Write the intercepts as ordered pairs)
Answer:
y = 2x -3
Step-by-step explanation:
y = 2x + b
plug the point in to the formula and solve for b
17 = 2 x 10 + b
b = -3
Use this to write the formula y = mx + b
m is slope
A point (-0.8, 0.6) will be a point on the unit circle in the second quadrant. Since it is a unit circle, its radius is 1, and we have
sin(α) = y = 0.6
cos(α) = x = -0.8
tan(α) = y/x = 0.6/-0.8 = -0.75
The angle is α = arccos(-0.8) ≈ 143.13°
______
For the unit circle, the trig values are always the coordinates or their ratio as shown above, regardless of quadrant.
