Answer:
The slope-intercept form of the function is:
Step-by-step explanation:
Given the table
x y
1 8
2 13
3 18
4 23
Let us take two points (1, 8) and (2, 13) to find the slope
- (1, 8)
- (2, 13)
We know that the slope-intercept form of the line equation is
where m is the slope and b is the y-intercept.
substituting the values m=5 and the point (1, 8) to determine the y-intercept i.e. 'b'.
8 = 5(1) + b
b = 8-5
Now, substituting the values m=5 and b=3 in the slope-intercept form to
Thus, the slope-intercept form of the function is:
Answer:
Step-by-step explanation:
I could show you how to solve it but it's a long process... basically calculate the area of the pyramid and the area of the rectangular prism individually and add them.
