y = mx + c
m is the slope of the graph and c is the y-intercept
In this case, m = 5 as stated in the question, so...
y = 5x + c
By substituting the given co-ordinates (-2,-1) into this equation, we can find c
-1 = 5(-2) + c
-1 = -10 + c
-1 + 10 = -10 + c + 10 (Add 10 to both sides)
9 = c
c = 9
Put c = 9 into the equation:
y = 5x + 9

Y=x will be on the point of the graph
Y= x+2 will be two units up but still positive so they will never interest
Step-by-step explanation:
Hey there!!
Let's check!
The equation are:
y=x
x - y = 0......(i).
y = x+2
x - y +2 =0......(i).
From equation (i).
Therefore the slopeof 1st equation is 1.
Now,
From 2nd equation.
Therefore the slope of equation 2 is 1.
As per the condition of parallel lines,
m1= m2
From both equation we got,
m1=m2=1
So, the lines are parallel.
For perpendicular,
m1×m2 = -1
1×1 is not equal to -1.
So, they are not perpendicular.
So,TheanswerisOptionA.
Hopeit helps....
