Answer:
y = 1/2x + 1
Step-by-step explanation:
The slope of the line is "rise"/"run", where "rise" is the vertical distance between two points separated by a horizontal distance of "run".
Here, two points are marked that are 4 units apart horizontally (run = 4). The right-most point is 2 units above the left-most point (rise = 2). The slope between these points is ...
m = rise/run = 2/4 = 1/2
The line crosses the y-axis at y=1, so the "y-intercept" is b=1.
These values can be put into the "slope-intercept form" equation for a line.
y = mx + b . . . . . . line with slope m and y-intercept b
y = 1/2x + 1 . . . . . matches the required answer form
Return is the answer. That's the gain or loss returned from the investment.
Since there is no value for either X or Y given, you can only change the formula around to equal X.
y=45x+38
First move the 38 to the left side by canceling it out (subtract 38 from both sides).
y-38=45x+38-38
So now we have:
y-38=45x
Now isolate the x on the right side by dividing both sides by 45.
(y-38) / 45 = x
So,
x = (y-38) / 45
(If the answer you’re looking for is a specific number, then the value for X or Y needs to be given!)

Answer & Step-by-step explanation:
The domain is the input, and the range is the output.
The domain is also known as the x values and the output as the y values (x,y).
So:
<em>domain: {4, -1, 0, 2}</em>
<em>range: {-4, 3, 5, 8}</em>
:Done
