If you meant "8 4/5," then that's "a mixed number."
Otherwise, both 8 and 4/5 are real numbers, and both are rationale.
Please be clearer about what you need to learn here.
Step 1: Find the slope:
To find the slope, find two points on the graph and count the “rise over run” between the points.
Two points here are (0,-1) and (2,1). To get from (0,-1) to the other point, you need to go “up 2” and then “right 2”. This means your slope is 2/2 or 1.
Step 2: Find the y-intercept:
We can see the y-intercept is (0,-1) on the graph. We’ll use the “-1” from that point for our equation.
Step 3: Put it all together:
The slope-intercept form is y=mx+b, where m is the slope and b is from the y-intercept.
Putting Step 1 and Step 2 into play, we have:
y = x - 1
Note: since m=1, we don’t need to write y = 1x -1. That 1 on the 1x is unnecessary.
To determine the equation that would be perpendicular with a certain line, we must first know the characteristics of a perpendicular line. This line would have a 90 degrees angle with another line so that the slope of this line would be the negative reciprocal of the slope of the other line. To write the equation, given a certain point we use the point-slope form of a line, y -y1 = m(x - x1).
Original line: <span>-x + 5y= 14
y = x/5 + 14/5
slope = 1/5
Perpendicular line's slope = -5
y - y1 = m (x - x1)
</span> y - (-2) = -5 (x - (-5))
y = -5x - 25 -2
y = -5x -27
