Answer:
slope = 25
y -intercept = 525
equation : y = 25x + 525
Step-by-step explanation:
An investor invests $525 in stock
It means the initial price of stock is $525
In 1 month increase in value of stock = $25
thus,
In x month increase in value of stock = $25x
Total cost of stock in x months = initial investment + increase in value of stock in x months
Total value of stock in x months = 525 + 25x
as Total value of stock in x months = f(x)
f(x) = 525 + 25x
it can be also written as
y = 25x + 525
____________________________________________
we know that slope intercept form of linear relationship is
y = mx + c
where m is the slope
and c is the y intercept
thus
comparing y = 25x + 525 with y = mx + c
we have m = 25
c = 525
