Ju chan solved the previous question by finding the expression 4(-15).

which addition problem would give the same result? choose all that apply.
15 + 15 + 15 + 15
4 + 4 + 4 + 4
(–1)(15 + 15 + 15 + 15)
(–15) + (–15) + (–15) + (–15)

(-1)(15+15+15+15)

(-15)+(-15)+(-15)+(-15)

Step-by-step explanation:

1. The multiplication shown in the problem above is:

4(-15)

The product is -60

4(-15)=-60

2. The multiplication above could indicate that:

- The number -15 is added 4 times.

- The number 15 is added 4 times and then is multiplied by -1.

- The number -4 is added 15 times.

- The number 4 is added 15 times and then is multiplied by -1.

 Keeping these on mind, you can conclude that the correct options are the third option and the last option:

(-1)(15+15+15+15)=(-1)(60)=-60

(-15)+(-15)+(-15)+(-15)=-15-15-15-15=-60

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
