1 Given the slope of a line is -2 and the point (-7,9). Write the linear equation in point slope
form. *

Step-by-step explanation:

equation is:

y= -2X + C

to find C use point (-7,9)

9=-2×-7 + C

C= -5

y= -2X -5

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.
