what is the equation for this graph it is rise/run slope and y-intercept
what is the equation for this graph it is rise/run slope and y-intercept
y=mx+b
b=y intercept
m=slope
yintercept is where the line crosses the y axis
looks like it crosses at -2
y=mx-2
take a point
how bout (1,0)
x=1
y=0
0=m(1)-2
add 2
2=m
the equation is
y=2x-2
