Find the x and y intercepts or any other 2 points. (I advise you finding the y intercept though.)
then calculate for slope using:
y(2) - y(1)
________
x(2) - x(1)
The (2) and (1) are not exponents they are small numbers at the bottom of the numbers.
The slope is: 4
You can use the trigonometric identity

.

The requirement that

eliminates -1/6 from being another solution.
Answer:
46
Step-by-step explanation:
just do -4x-4=16 then 6x5=30 than add 16+30 =46
A. y=5+1.5d
b. after 20 days it will be 5+ 1.5 × 20 = 5+ 30= 35 cm
