Can someone explain y-intercept? I had a test, and I am pretty sure I bombed it. I really need help!!
Dvinal [7]

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!

refer to the diagram of a right triangle to solve this problem : find a and b correct ro the nearest hundreth. a=b,c=60. Explain
OlgaM077 [116]
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
