Please help out with this worksheet please i would appreciate it

Answer:

1. slope: (y2-y1)/(x2-x1)

(6,38), (9,32)

(32-38)/(9-6) = -6/3 = -2

38 = -2(6) + b

38 = -12 +b, b = 50

y = -2x + 50

2a. Slope = -80, the slope means how many cars left per hour after closing. Y- intercept = 600, cars in lot during closing.

2b. use the equation: y = -80x + 600

Plug in 3 into the equation

y = -80(3) + 600, y = -240 + 600, y = 360 cars

2c. For it to have 0 cars, plug in 0 for y

0 = -80x + 600

-600 = -80x, solve for x

x = 7.5 hours

Which equation has a slope of 1/2 and passes through the point (1.2)?
Naya [18.7K]

Answer:

The answer is

<h2>x - 2y + 3 = 0</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of a line given a point and slope we use the formula

y - y1 = m(x - x1)

where

m is the slope

( x1 , y1) is the point

From the question the point is ( 1 , 2) and the slope is 1/2

Substitute the values into the above formula and solve for the equation

That's

<h3>y - 2 =  \frac{1}{2} (x - 1) \\ 2y - 4 = x - 1 \\ x - 2y - 1 + 4 = 0</h3>

We have the final answer as

<h3>x  - 2y + 3 = 0</h3>

Hope this helps you
