Write an equation for the line through the point -6 and -1 and parallel to the line 3x + y equals negative 7. write your answer in slope intercept form

y = -3x - 19

Step-by-step explanation:

The line passes trough (-6,-1)

The line is parallel to line whose equation is 3x + y = -7

Writing the equation of this parallel line in slope intercept form:

y = -3x - 7

Because the two lines are parallel, their slopes are the same.

Since the slope(m) is -3, equation of our first line will be:

Slope(m) = Change in y ÷ change in x

Taking another point (x,y) lying on our first line:

-3 = =

Cross multiplying gives;

y + 1 = -3x - 18

y = -3x - 19

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
