Answer:

y = 2x - 1

Step-by-step explanation:

Slope intercept form: y=mx+b

point a: (1, 1)

point b: (2, 3)

1. Find the slope of the equation

Equation for slope(mx): (y2- y1)/ (x2-x1)

(3-1)/(2-1)= 2

slope: 2

2. Pick any of the two point to find the "b" and plug in the coordinates of the point to find the y-intercept of the equation.

point a: y=1, x=1

y=mx+b

1=2(1) + b

b= -1

3. Plug the answers you found above into the slope-intercept form

Overall equation:

y=2x - 1

On a trip, you had to change your money from dollars to British pounds. You got 560 pounds for 800 dollars. How many pounds will
leva [86]
<h2>Answer</h2>

210 pounds

<h2>Explanation </h2>

First, we are going to find the exchange rate from dollars to pounds.

We know form our problem that 800 dollars are 560 pounds. so:

\frac{560pounds}{800dollars} =0.7 pounds per dollar.

Next, we are going to multiply our exchange rate by the number of dollars we want to change, 300:

300dollars*\frac{0.7pounds}{dollar} =210pounds

We will get 210 pounds for 300 dollars
