Write a rule for the inward function whose graph has a slope m=2, and a y-intercept b=-4

Step-by-step explanation:

The slope is given as m = 2

The general equation is y = mx + b

So far what we have is   y = 2x + b

The y intercept is the value of y when x = 0

-4 = 2(0) + b

b = - 4

Therefore the equation is y = 2x - 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.
