Answer:
line graph
Step-by-step explanation:
for 6
in a
given
slope(m)=1
point=(2,-4)=(x1,y1)
we know
equation of straight line
y-y1=m(x-x1)
y+4=1(x-2)
y+4=x-2
therefore x-y-6=0 is the required equation
substituting with ax+by+c=0 we get
a=1
b= -1
c= -6
f(5) = 2
<u>Given: </u>
<u>For x=5 :</u>
=
= 2
