What is the equation of a line that is parallel to the x-axis and passes through the point (2,-1)

y = - 1

Step-by-step explanation:

the equation of a line parallel to the x-axis has equation

y = c

where c is the value of the y-coordinates the line passes through

the line passes through the point (2, - 1) with c = - 1

y = - 1 ← is the equation of the horizontal line

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

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.
