If the interest is fixed, the answer is A.
Step-by-step explanation:
I'm going to explain this in standard slope intercept form (y=mx+b) because it is easiest for this situation. I will also include converting it to point slope form. I will also show how to do straight into point slope form if you find that more helpful.
First thing is to identify difference in x and y in both points. From point 1 to point to, the x changes -4 and the y changes +4. We can rapresent this in rise over run fraction
So the slope is -1 because the slope is the simplified rise over run fraction.
Our next step is to find the y-intercept. This is easy because the first point is the y-intercept, so -3 is our y-intercept.
Now we know the equation.
All we have to do now is convert it into point-slope form. So here is point slope form: y + y1 = m(x + x1). Y1 is the y-intercept and m is the slope.
So x1 is the x intercept, so to find this you find the x value when y is 0. You can do this by using the standard form I've done because it is easiest.
So when y is 0, then x is -3. Here is the complete point slope form of the line.
-----------------------------------------------------
To put the line directly into point slope for you need to find the slope, y-intercept, and x-intercept and place the values in accordingly. If you aren't given the y-intercept and x-intercept straight away it can be difficult for some putting it directly in point slope form. That is why I recommend putting it into standard form then point-slope form.
Answer:
Step-by-step explanation:
income elasticity of demand for the good X = % change in quantity demanded / % change in income of consumer = - 15 / 2 = - 7.50 negative since it is a decrease in demand.
and the good X is an inferior good since increase income brings about a decrease in quantity demanded of the goods compared to normal good where a decrease in income brings about decrease in quantity demanded and an increase in income brings about increase in quantity demanded.
I'm assuming the blueprint shows 1 inch is equal to 10 ft. This means that 1 inch on the blueprint corresponds to 10 feet in real life.
We have the ratio
1 inch: 10 feet
If we multiply both sides by 0.5 then,
0.5*(1 inch) : 0.5*(10 ft)
0.5 inch : 5 feet
So 0.5 inches (aka half an inch) on the blueprint corresponds to 5 feet in real life.
Answer: A) 5 feet
