Equation of a line with a slope of 1/4 and an x-intercept of 8

Mathematics

GarryVolchara [31]3 years ago

First, we can start with the equation of a line

y = mx + b

We are given the slope, m = 1/4. Plug this into our function

y = 1/4 x + b

Now we need to find b (y-intercept). We are given the x-intercept, where the line crosses the x-axis. So we know the value of y = 0 at the x-intercept. This point is (8,0). We can plug this value into our equation above (since we know this point is on the line) and solve for b.

0 = 1/4(8) + b
0 = 2 + b
b = -2

Plug this b value into the equation we were building for our final equation

y = 1/4 x - 2

If $1,000 is invested in an account that pays 5% interest compound annually, an expression that represents the amount in the acc
KengaRu [80]
Hello! So the formula for compound interest is P(1 + r)^t, where r = rate, P = principal, and t = time (years). C is out, because you multiply the rate and principal together to get the price, not add. You raise the decimal to a certain power, based on the amount of years. You add 1 to the rate. 5% in decimal form is 0.05 and you must add 1 to the amount, which eliminated B. The only answer that works is A, because it shows the correct formula. The answer is A.

How many 5-minute calls can you make if your phone plan gives you 200 minutes per month?
Inessa [10]

Answer:

40 minutes

Step-by-step explanation:

You can simply make 200/5 = 40 5 minute calls per month.

This works because every call is a 5-minute call.  So then we just have to find how many times we can make a 5-minute call up to 200 minutes.  We already have an operation for this: Division.  This acts as the opposite of multiplication and speeds our process up.

 A movie theater sends out a coupon for 85​% off the price of a ticket. Write an equation for the​ situation, where y is the pri
ra1l [238]

Answer:

y=0.15x

Step-by-step explanation:

Given:

Original price of the ticket is x

Price after using the coupon is y

Coupon discount is 85% of x=0.85x

Therefore, the price after applying coupon is given as the difference of the original price and the coupon discount. That is,

y=x-0.85x=x(1-0.85)=0.15x\\\therefore y=0.15x

The graph is shown below. The graph passes through the origin as the above relationship is a proportional relationship.

The line y=0.15x strictly remains in the first quadrant as both x and y can't be negative as they represent price of tickets and price can never have negative values. Hence, only the first quadrant has both the values of x and y positive.
