Answer: y = 3x + 1
<u>Step-by-step explanation:</u>
The equation is in Slope-Intercept format: y = mx + b where
- m is the slope <em>(difference in y's over difference in x's)</em>
- b is the y-intercept <em>(value of y when x = 0)</em>

b = 1 <em>refer to the table that shows y = 1 when x = 0</em>
Now input m = 3 and b = 1 into the Slope-Intercept formula:
y = 3x + 1
(0, 3)
<span>-x + 3y=9
to figure out the y-intercept, you must put the equation into y-intercept form first: y = mx + b
</span><span>-x+3y=9
3y = x + 9
y = (x/3) + (9/3)
y = x/3 + 3

Answer:
answer = -13
Step-by-step explanation:
number = x
x - 8 = -21
x = -21 + 8
= -13
Recheck :
num = - 13
decreased by 8 = - 13 -8 = -21
It would be 20.15 because the 65% of 31 is 20.15
The answer is A.
Ordered pairs that equate to a function would not have two separate points with the same x-value. In other words, every x-value must be associated with only one y-value.
