Answer: y=-13/12x-7
Step-by-step explanation:
To find the slope-intercept form, we first need to find the slope. To find the slope, you use the formula . We use the two given points to find the slope.
Now that we have our slope, we can start filling out the slope-intercept form equation.
y=mx+b
y=-13/12x+b
Since we don't know the y-intercept, we can use one of the given points and solve for b.
6=(-13/12)(-12)+b [multiply (-13/12) and -12]
6=13+b [subtract both sides by 13]
b=-7
With the y-intercept, we can complete our equation.
y=-13/12x-7
Answer:
-2, compliments
Step-by-step explanation:
The computation of the cross elasticity of demand is shown below:
Given that
(P1, Q1) = (7, 25)
(P2, Q2) =(5,50)
Now here we use the mid-point formula for determining the cross price elasticity
= [(Q2 - Q1) ÷ (P2 - P1)} × [(P1 + P2) ÷ (Q1 + Q2)]
= [(50 - 25) ÷ (5 - 7)] × (5 + 7) ÷ [(25 + 50)]
= -2
Hence, the cross-price elasticity is -2
It is negative so these are complementary goods
Hence, the correct answer is -2, compliments
