Answer:
The equation of the line with a y-intercept of 4 and a point (8,8) is 
Step-by-step explanation:
A linear equation can be expressed in the form
y = m * x + b
where x and y are coordinates of a point, m is the slope and b is the y-intercept. Since this equation describes a line in terms of its slope and its y-intercept, this equation is said to be in its slope-intercept form.
Graphically this equation represents a line.
In this case, you know:
- The point (x,y)=(8,8)
- Y-intercept= 4
Replacing:
8=m*8 +4
Solving:
8-4=m*8
4=m*8
4÷8= m

Then, <u><em>the equation of the line with a y-intercept of 4 and a point (8,8) is </em></u>

Answer:
For the first answer, I believe it to be A.
Step-by-step explanation:
For the top question, the only one that could come after 0.038 would be A.
Answer:
Sin0= y/r
X= -4 and r= 9 (radius is also the hypotenuse)
In quadrant II y is positive
X^2 +y^2 = r^2
-4^2 + y^2 = 9^2
16 + y^2 = 81
Y^2 = 81-16
Y^2 = 65
Y= sqrt65
Sin0= sqrt65/9

Answer:
3.49
Step-by-step explanation:
The growth factor is one more than the growth rate:
growth factor = 1 + growth rate
= 1 + 249% = 1 +2.49
growth factor = 3.49
