Answer:
any coordinate outside the parabola is a reasonable answer.
Step-by-step explanation:
test the solution (0, 0) and if if that number is greater than 0 then the rest of the points outside on the inside are.
x = 0
y = 0
(0)^2 - 2(0) - 3 = -3
-3 is less than 0 so (0, 0) is not a possibility so any coordinate outside the parabola is a reasonable answer.
 
        
             
        
        
        
Answer: 5 calories = 1 cracker
Step-by-step explanation:
60:12 = 5:1
60 calories and 12 crackers = 5 calories and 1 cracker
 
        
             
        
        
        
B. they are directly proportional because she keeps taking 3 at a time to his 1 at a time.
        
                    
             
        
        
        
Answer:
y = x + 3 
Step-by-step explanation:
Slope-intercept form is represented by the formula  . We can write an equation in point-slope form first, then convert it to that form.
. We can write an equation in point-slope form first, then convert it to that form. 
1) First, find the slope of the line. Use the slope formula   and substitute the x and y values of the given points into it. Then, simplify to find the slope, or
 and substitute the x and y values of the given points into it. Then, simplify to find the slope, or  :
: 
 
 
Thus, the slope of the line must be 1. 
2) Now, since we know a point the line intersects and its slope, use the point-slope formula  and substitute values for
 and substitute values for  ,
,  , and
, and  . From there, we can convert the equation into slope-intercept form.
. From there, we can convert the equation into slope-intercept form. 
Since  represents the slope, substitute 1 in its place. Since
 represents the slope, substitute 1 in its place. Since  and
 and  represent the x and y values of a point the line intersects, choose any one of the given points (either one is fine) and substitute its x and y values into the equation, too. (I chose (0,3).) Finally, isolate y to find the answer:
