What will happen to the graph of the line y = 3/4x – 7 if you change 3/4 to −3/4?

Below.

Step-by-step explanation:

The slope is given by the coefficient of x (= 3/4) .

If the slope changes to -3/4 the line will slope in the opposite direction.

If the slope is 3/4(positive)  it rises to the right and if it is -3/4 it will rise to the left, but will rise at the same rate.

The 2 lines will cross each other  when 3/4x - 7 = -3/4x - 7:

3/4x - 7 = -3/4x - 7

6/4 x = 0

x = 0

So they will cross at the point (0, -7).

plz mark brainliest i took the test

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
