Can you help me with 4 through 6 plz
Crazy boy [7]
Example 4:

Let y = ax + b

Where, a = 4

Then,

y = 4x + b

As we have one point = (-2,3)

Replace in the equation:

3 = 4(-2) + b

3 = -8 + b

b = 3 +8

b = 11

So us stay:

y = 4x + 11
________________

Now let's to the 5 example:

Let y = ax + b

Where a = 3/2

Then,

y = 3x/2 + b

As the point is = (4, 7)

Then we will stay:

7 = 3(4)/2 + b

7 = 6 + b

b = 7 - 6

b = 1

Then we will stay:

y = 3x/2 + 1
______________


Now let's to the last example:

Let y = ax + b

Where , a = -4/3

Then we going to stay with:

y = -4x/3 + b

As the point is = (6 , -2)

Then,

-2 = -4(6)/3 + b

-2 = -8 + b

b = -2 + 8

b = 6

So follow:

y = -4x/3 + 6
