3question they are together
1: y=2x+15
2x+3y=5

2: 6x+10=14
-7x-10y=-18

3: 16x-8=16
-8x-y=22

(-5,5) , (1.5 , -34) , ( 3/4, -1.3)

Step-by-step explanation:

I hope I solved it right

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
