Since you know the x and y values, you just have to plug these into the linear slope-intercept equation:
y = mx + b
-10 = m(1) + b
m + b = -10
b = -10 - m
Now that we have a value for b, we can plug this into the other equation:
8 = m(-8) + b
8 = -8m + (-10 - m)
8 = -9m -10
18 = -9m
m = -2
Now that we know what m is equal to, we can plug this into our first equation to get an answer for b:
b = -10 - m
b = -10 -(-2)
b = -10 + 2
b = -8
Our final equation is y = -2x - 8
If we use 22/7 as pi we can say...
22/7 / 90 =
22/7 x 1/90 =
22/630 = 11/315 (in fraction form)
11/315 is the same as saying 11 divided by 315 which would work out to
about .035 rounded to the nearest thousandth
-4 or
Rise 4 and run 1 to the left (that's what makes it negative)
For this case we have that by definition, the slope of a line is given by:
Where:
and are two points through which the line passes.
