How do you know the correct order in which to evaluate algebraic expressions?

and that you would use for a .

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

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.

answer is because 4×10=40

and 98×4= is 392

40,392
