Answer:
<h2>The answer is - 2</h2>Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the slope we must first write the equation in the general equation above
That's
6x + 3y = 15
<u>Make y the subject</u>
Send 6x to the other side of the equation
3y = - 6x + 15
<u>Divide both sides by 3</u>
We have
y = - 2x + 5
Comparing with the general equation above
Slope / m = - 2

Answer:
And then we can find the y intercept using one point for example (0,800) and we have:
And our model would be:
And the x intercept would be if y=0 then
x intercept =400 represent the value of x when y =0
y intercept = 800 represent the value of y when x =0
Step-by-step explanation:
We have the following points given:
(0, 800) and (400, 0)
If we want to find the x intercept and y intercept we need to remember that we need to set a linear model given by:
Where
And then we can find the y intercept using one point for example (0,800) and we have:
And our model would be:
And the x intercept would be if y=0 then
x intercept =400 represent the value of x when y =0
y intercept = 800 represent the value of y when x =0
