Question 176200
to write this equation we need the slope which is {{{DELTA(y)/DELTA(x)}}}=change in y over change in x=rise/run=m=slope
:
9-0/0-10=-9/10=m(slope)
:
now choose any point on the line and use the point slope formula. I choose (0,9)
:
y-9=(-9/10)(x-0)
:
y-9=-9/10x.
:
y=-9/10x+9 (slope intercept form)
