-2 -1 0 1 2
The 4 arrows above the number line represents the distance between 2 and -2 which is 4!
Answer:
(0, 4)
Step-by-step explanation:
Look carefully at the y-axis. What is the y-coordinate where the curve crosses the y-axis? It's y = 4. Thus, the y-intercept is (0, 4).
It just so happens that (0, 4) is also the maximum of the function represented here.
Answer:
y = -1/6x +2
Step-by-step explanation:
The black vertical line in the middle of the graph is the y-axis. The blue line crosses it a the point marked 2. This is known as the y-intercept.
The slope of the line is the ratio of "rise" (vertical change) to "run" (horizontal change).
There is a marked point on the line at the y-intercept, where x=0 and y=2. There is another marked point to the right of that, where x=6 and y=1.
The vertical change between those two points is 1 -2 = -1.
The horizontal change between those two points is 6 -0 = 6
The slope is then -1/6.
__
The slope-intercept form of the equation of a line is often written as ...
y = mx + b
where "m" is the slope (-1/6), and "b" is the y-intercept.
Using the values we found above, the equation of the line is ...
y = -1/6x +2
