Math what's the equation in function notation

y = 1 , y = x

Step-by-step explanation:

Consider the line with points (0,1) and (2,1)

Slope of a straight line = change in y ÷ change in x

Slope of this line = = 0

Taking another point (x,y) on the line;

Slope =   = 0

y - 1 = (x - 2)0

y = 1 (and this is the equation of the line)

Consider the line which passes through points (-1,-1) and (0,0)

Slope = = 1

Taking another point (x,y) on the line;

slope = = 1

y = x  (and this is the equation of our second line)

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

5/20 so 25%
