You need to know where the line crosses the y axis (vertical) - AKA the y intercept, and the slope of the line.
The y intercept is 5. The slope is -1/3 because every time the line goes down one square, it also goes right three squares.
Equation:
y=mx+b
where m is the slope and b is the y intercept
y = 1/3x + 5
Another way to write the same thing
y = x/3 + 5
Both correct!
Answer:
6
Step-by-step explanation:
if y-intercept is 8, means when x = 0, y = 8
8 = 2(− 1)^2 + k
8 = 2 + k
k = 6
The surface are is about 161.6 square centimeters.
