Answer:
<u>y = -3x - 0.25</u>
Step-by-step explanation:
Write the equation of a line that has a slope of -3 and passes through the point (1.25, -4).
We'll use the point-slope form of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).
We are told the slope, m, is -3.
y = -3x + b
We need to find a value for b that will cause the line to go through point (1.25,-4), We can do that by entering this point in the equation we have this far:
y = -3x + b
-4 = -3(1.25) + b
-4 = -3.75 + b
-0.25 = b
<u>The equation is: y = -3x - 0.25</u>
<u></u>

The way a proportion is set is as follows;
The Distance from Rio de Janeiro and San Jose Costa Rica is then found as 800 miles
Step-by-step explanation:
The dimension of the distance between Rio de Janeiro and San Jose Costa Rica = 4 inches
The map scale = 1 inch to 200 miles
To figure out how many miles it is or the actual distance from Rio de Janeiro and San Jose Costa Rica, we have;
Therefore, we have;
(4 inches × 200 miles)/(1 inche) = Distance from Rio de Janeiro and San Jose Costa Rica
Which gives;
Distance from Rio de Janeiro and San Jose Costa Rica = 800 miles.
