Answer:
(22,0)
Step-by-step explanation:
1. Select any two points given and find their slope (rise/run)
(-38, 40) and (-23, 30)
slope = = - 2/3
2. Use the slope and one of the points to create an equation of the line in the format y = mx + b, where m = slope and b = y-intercept.
y = mx + b ⇒ 40 = -2/3 (-38) + b
3. Solve for b
40 = -2/3 (-38) + b
40 = 76/3 + b
40 - 76/3 = b
b = 44/3
4. To find the x-intercept, set y = 0, and solve.
y = -2/3 x + 44/3
0 = -2/3 x + 44/3
2/3 x = 44/3
x = 22

Step-by-step explanation:
Do you mean or
?
Use the formula where
is the amplitude,
is the phase shift,
is the vertical shift, and the period is
.
Assuming your first case is true, the amplitude would be , your period is
, and your midline/vertical shift is
.
Assuming your second case is true, everything but the vertical shift stays the same. It would be in this case.
