For the graph,

43. y=2.5x−4

45. y=−15x+3

47. y=12x+−94

Step-by-step explanation:

43.

Let's solve for x.

y=2.5x−4

Step 1: Flip the equation.

2.5x−4=y

Step 2: Add 4 to both sides.

2.5x−4+4=y+4

2.5x=y+4

Step 3: Divide both sides by 2.5.

2.5x2.5=y+42.5

x=0.4y+1.6

x=0.4y+1.6

45.

Let's solve for x.

y+15x=3

Step 1: Add -y to both sides.

15x+y+−y=3+−y

15x=−y+3

Step 2: Divide both sides by 1/5.

15x15=−y+315

x=−5y+15

x=−5y+15

47.

Let's solve for x.

2x−3=4y+6

Step 1: Add 3 to both sides.

2x−3+3=4y+6+3

2x=4y+9

Step 2: Divide both sides by 2.

2x2=4y+92

x=2y+92

x=2y+92
