Hi! can anybody me with these problems? i have to do 2 step equations. 1. 3.8x + 5.2x - 6.7 = 11.3 2. 7.8y - 4.9 - 5.4y = 2.3 3. 2/3x - 5 = 1 4. 7/5y = 3 - 1/5 there are pictures below for the ones that have fractions ( 3 and 4)

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.
