There is no line provided but here is how to do it.
Assuming you mean a line on a graph, it would likely have a slope, y-intercept, and x-intercept. In the most unlikely case, it would be in a horizontal or vertical direction which mean that the slope would be zero and undefined.
To make a slope-intercept equation out of a line on a graph use the format:
y = mx + b
M = the slope
B = y-intercept
Quick heads up: The x-intercept is not included in slope-intercept but is in the point-slope format. But personally, I believe the slope-intercept is easier format to understand (could be different from your perspective though).
So the y-intercept is like the beginning of a line or when the line intersects in the y-axis and the x-value of a ordered pair is 0.
To give an example, take a look at this ordered pair:
(0, 5)
In this ordered pair, the x-value is 0 and the y-value is 5. The 5 is the y-intercept because the x-value is 0.
So now onto the slope.
To calculate the slope, find two random ordered pairs on the line.
Then using the formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Calculate the slope.
To give a better understanding, the second ordered pairs y-value should be plugged in first and the first one lastly. Do the same for the x-value and divide. Then you should get the slope (sometimes it's easier to leave as a fraction since decimals can go on "forever.")
Now that the slope and y-intercept have been calculated, simply plug in everything.
As Mentioned before using the format y = mx + b for slope-intercept form.
Here's an example equation:
y = 0.5 + 5
The slope is 0.5 and the y-intercept and 5.
