Answer:
a) black line, y= 3x+2 blue line, y=-3x+8
b) the coordinates at which the two graphs intersect. That is (1 , 5)
c) Substituting the two equations then finding the respective values
Explanation:
c) y=y
or,3x+2=-3x+8
or, 3x+3x= 8-2
or, 6x= 6
∴ x= 1
Now, substitute the value of x in either of the equations, both will output the same value for y.
y= 3x+2
= 3×1 +2
= 5
intersecting point( 1 , 5)
