Answer:
Option D. A student who studies 0 hours can expect to score about a 60 on the test
Step-by-step explanation:
we know that
The y-intercept is the value of the y-coordinate when the value of the x-coordinate is equal to zero
In this problem
The x-coordinate represent the hours spent studying
The y-coordinate represent the Test score
so
For x=0, y=60
That means
A student who studies 0 hours can expect to score about a 60 on the test

Answer:
x=3 and y=12
Step-by-step explanation:
equation:1
equation:2
Solving equation:1 for 'y' in terms of x
equation:3
Putting 'y' in equation:2 which will make the equation of the single variable


Putting value of 'x' in equation:3 to find 'y'


Answer:
y = 1/2x + 8
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - 10 / 2 - 4
-1 / -2
= 1/2
y = 1/2x + b
10 = 1/2(4) + b
10 = 2 + b
8 = b
Answer:
They are the same
Step-by-step explanation:
A kilometer is 1000 meters, so you multiply 45 by 1000, to get 45000.
