You can put this solution on YOUR website! One way to represent a line using algebra, is with the slope-intercept equation of a line. This means: y=mx+b.
y and x is a particular point on the line.
m is the slope and, b is where the line crosses the y-axis.
.
So, in your example the slope = m = 10
You can find the slope when you're given an equation in the form y=mx+b,
m is the slope, b is the y-intercept.
The equation you've been given is y=10x-5.5
10 is m and -5.5 is b.
