What is the equation of the line that passes through the points (3,-13) and (-2,7)

y = -4x - 1

Step-by-step explanation:

As we move from the point (-2, 7) to the point (3, -13), x increases by 5 and y decreases by 20.  Hence, the slope of this line is m = rise/run = -20/5, or -4.

Starting with the slope-intercept formula for a straight line:

y = mx + b.  We substitute -4 for m, -13 for y and 3 for x:

-13 = (-4)(3) + b, so b = -1, and the desired equation is:

y = -4x - 1

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
