Y=mx+b is the equation we must fill out, with x and y being their respective coordinates, m being the slope, and b being the y-intercept. The y intercept will be at (0, y), and the beginning of this problem already gives us the y-intercept: -4.

We now know y=mx-4. To find the slope, m, we’ll plug in one of the coordinates: (5, 1). The new equation is 1=m(5)-4. Solve this to get 5=m(5), and then m=1.

Now that we know the slope and y-intercept, we can conclude that the equation is y=x-4.

A square pyramid is sliced parallel to the base and halfway up the pyramid.
Anna [14]

Answer:

A square smaller than the base

Explanation:

A square pyramid is a 3 Dimensional image. When you slice a 3 Dimensional image you form is a 2 Dimensional image for example a rectangle, a square, a triangle e.t.c.

The shape of the cross sections formed after slicing a 3 Dimensional image is dependent on the way it was sliced.

This means it can be sliced horizontally or vertically and this would result in different shapes.

If square pyramid is sliced parallel to the base and halfway up the pyramid, the shape of the cross section formed is a square smaller than the base.

If you 30,400 people died in 2015, how many deaths per hour
Soloha48 [4]

well, let's assume you haven't been dead for 3 years then, 30,400 a year, expressed as a unit rate per hour?

assuming a year has 365 days.

a day has 24 hours, therefore a year will have 365*24 hours.

so 30400 per year, will be 30400/(365*24) per hour, namely about 3.47031963, which we can round up to about 3 deaths per hour.

Greg drove 660 miles in 12 hours. At the same rate, how long would it take him to drive 495 miles?
Slav-nsk [51]

This one has two parts, first we have to find out the speed to drive 660 miles in 12 hours.  Divide 660 by 12 to get the speed of 55 miles per hour, that is your rate for the next part.

Next we need to find out how long it will take to drive 495 miles at the same pace of 55 mph.

Do the same thing 495/55.  That will give you your final answer.

495/55= 9

It will take him 9 hours to drive 495 miles at a rate of 55 mph.
