Pls help! I need help with a and c I did b already!
laila [671]

Answer:

A= y= -2x+7.

B= y= -\frac{3}{2}x+ 6

Step-by-step explanation:

The linear equation is y=mx+b

A= y= -2x+7.

-2 represents he slope and 7 represents the y intercept.

B= y= -\frac{3}{2}x+ 6

-\frac{3}{2} is the slop and 6 is the y intercept.

Hope this helps :)

Help me out pleaseee ​

Answer:

Option B is the correct choice.

Step-by-step explanation:

The graph is attached below.

We have to find the x intercept meaning the value of the point onx-axis when y=0

So we will put the value of zero (0) instead of y in our given equation.

So here we have solved it algebraically.

y=\frac{3}{4}x-3

Putting y=0

0=\frac{3}{4}x-3

0=\frac{3x-12}{4}

Multiplying 4 both sides.

0=3x-12

Adding 12both sides.

12=3x

Dividing with 3 both sides.

x=\frac{12}{3}=4

So the x-intercept of the given equation is 4 which can be written as (4,0) in terms of coordinates.

Option B (4,0) is the correct choice.
