-9(m)=-1
m=1\9
5-Y=1\9(x-5)
-Y=1\9x-5\9-5
Y=-(1\9x-50\9)
y=-1\9x+50\9
9y=X+50
m=1\9
5-Y=1\9(x-5)
-Y=1\9x-5\9-5
Y=-(1\9x-50\9)
y=-1\9x+50\9
9y=X+50
y = - 9x + 50
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 9x + 2 is in this form with slope m = - 9
Parallel lines have equal slopes
y = - 9x + c is the partial equation of the parallel line
To find c substitute (5, 5 ) into the partial equation
5 = - 45 + c ⇒ c = 5 + 45 = 50
y = - 9x + 50 ← equation of parallel line
