Write the equation, in general form, of a line with a slope of 1 and a y-intercept of -1. a. x - y = 1
b. -x + y = -1
c. -x + y + 1 = 0
d. x - y - 1 = 0
pls help asap !!!

Plug in numbers.

Step-by-step explanation:

using the equation of a line, y=mx+b, m is slope and b is the y-intercept. y and x are the coordinates. So graph the line first. It has a slope of one and the y-intercept is -1. Then plug in numbers for the equation. Make sure they are reasonable.

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.
