Answer:

y = -x+2

Step-by-step explanation:

The y intercept is 2

The slope is found by using 2 point

I picked (0,2) and (2,0)

m = ( y2-y1)/(x2-x1)

= ( 0-2)/(2-0)

= -2/2 = -1

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -1x+2

y = -x+2

Answer:

If we ignore the fact that Function 2 has a negative slope, then Function 2 has the greater rate of change.

Step-by-step explanation:

Function 1 has the rate of change m = 2/5, because every increase of 2 in y occurs in conjunction with an increase in x of 5.

Function 2 is a decreasing function (that is, its slope is negative). As we move from (0, 3) to (4.5, 0), x increases by 4.5 and y decreases by 3. Hence, the slope of Function 2 is m = rise / run = -3/4.5, or m = -2/3.

The absolute values of the slopes of the two functions are 2/5 and 2/3 respectively. If we ignore the fact that Function 2 has a negative slope, then Function 2 has the greater rate of change.

But if we take into account the signed number -2/3, then Function 1 has the greater slope because it's positive whereas that of Function 2 is negative.
