F(x) = -4x - 5
Subtitute the value of x to the equation:
f(-1) = -4 · (-1) - 5 = 4 - 5 = -1
Y-intercept, it can be described as y-intercept form, or another way of writing it in mathematical form is y=mx+b, this can be used to draw polygons, find ortho-centers (very difficult), etc. m is the rise/run, rise over run, or 1/2. The rise and the run is the rate of change. b is the starting point or slope where it starts at, that is most of it!
Use Pythagorem theorem (Sorry I can't spell)
but use one variable (a) since a and b are same
60=a^2+a^2
60=2a^2
30=a^2
a=square root of 30
a= 5.48 (round to nearest 100)
since a and b are same, they are 5.48
note that a^2 means a to the power of 2
