Answer:
y=-3x+10
Step-by-step explanation:
Slope formula y2-y1/x2-x1
7-1/1-3
simplify
6/-2
simplify
-3
now plug -3 into y=mx+b
y=-3(x)+b
choose any point and plug it into the equation, I am using (3,1)
1=-3(3)+b
simplify
1=-9+b
add 9 to both sides
b=10
plug into slope-intercept form
y=-3x+10
For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following points through which the line passes:

We find the slope of the line:

Thus, the equation of the line is of the form:

We substitute one of the points and find b:

Finally, the equation is:

Good evening ,
Answer:
<h2>8 chickens</h2><h2>8 horses</h2>
Step-by-step explanation:
let c = the number of chickens
let h = the number of horses
You have to solve this system
h + c = 16
4h + 2c = 48
h + c = 16 ⇒ h = 16 - c
If we substitute h=16-c in the second equation we will get :
4(16-c)+ 2c = 48
Then 64 - 4c + 2c = 48
Then 2c = 64 - 48 = 16
Then c = 8
Since h = 16 - c then h = 16 - 8 = 8
