The point-slope form of the line:

We have the slope m = -2 and the point (4, -3). Substitute:

Answer:
Cost of the 5 pounds of Ashmend’s kernel apples is $7.5
Step-by-step explanation:
As given
At a local farmer’s market , Jodi bought 3 pounds of Ashmead’s kernel Apples for $4.47 at the McDougal Orchards stand .
i.e
3 pounds = $ 4.47
Now find out the cost of 1 pound of Ashmend kernel apples .

= $ 1.5 (Approx)
Cost of 5 pounds of Ashmend’s kernel apples = Amount of apples × Cost of 1 pounds of apples .
= 5 × 1.5
= $ 7.5
Therefore the cost of the 5 pounds of Ashmend’s kernel apples is $7.5 .

Step-by-step explanation:
The standard form for an equation is y=mx+b. You find the slope by using the formula of rise over run. This means that for problem 6 you first look to see if its positive or negative slope. The slope is positive if the line is going uphill and if its going downhill its negative. The slope would be negative for number 6 because it is going downhill. Then for the actualy slope you would start with rise. So you look at the point (0,1) and go up 3 until you hit the line of the other point and run over 2. So your slope would be -3/2.
The equation represents height as a function of time.
The bullet was in the air for 75 seconds.
The equation is given as:

The time spent in the air is the time it takes the bullet to land on the ground.
When the bullet is on the ground, the height is:

So, we have:


Factor out t

Split
or 
represents when the shot is fired.
So, we solve for t in 
Collect like terms

Divide both sides by 16

Hence, the bullet was in the air for 75 seconds
