Step-by-step explanation:
a=A=169=13
The answer is C my friend
the third graph is y = - 5x + 1
The equation of a line in ' slope- intercept form ' is
y = mx + c ( m is the slope and c the y-intercept )
y = - 5x + 1 is in this form with m = - 5 and c = 1
Since the slope is negative the line will slope down from left to right.
Graphs 3/4 are the only 2 which slope down
Both graphs have a y -intercept of 1
Only graph 3 has a slope of - 5
check using the points (0 ,1 ) and ( 1, - 4 )
I don't know if i'm right or wrong but I tried.
It has to be perpendicular because parallel lines are straight.
For example:
__________>
__________>
Perpendicular lines look like this:
X
Perpendicular lines touch and parallel lines don't touch.
