2 1/2 * 3 

5/2 * 3/1

= 15/2 

15/2 - 11 3/8

15/2 - 91/8 
 
91/8 - 60/8

= 31/8 = 7 7/8

answer=7 7/8

The graph of a linear relationship has a slope of -5 and passes through the point (2, -12). Write the equation of the line in sl
DerKrebs [107]
<h3>Answer:</h3>

y=-5x-2

<h3>Solution:</h3>
  • We are given the line's slope and a point that it passes through.
  • Using the given information, we can write the equation of the line in Point-Slope Form:
  • y-y_1=m(x-x_1)
  • In this formula, y₁ stands for the y-coordinate of the point, m stands for the slope of the line, and x₁ stands for the x-coordinate of the point.
  • In this case, y₁ is equal to -12, m is equal to -5, and x₁ is equal to 2.
  • Plug in the values:
  • y-(-12)=-5(x-2)
  • y+12=-5(x-2)
  • Now, convert into Slope-Intercept Form, y=mx+b:
  • y+12=-5x+10
  • y=-5x+10-12
  • y=-5x-2

Hope it helps.

(4,-2) and (24,-17) finding the slope from points
Romashka [77]
Use the equation for the slope:
slope = \frac{y2-y1}{x2-x1}
The two points are equal to (x1, y1) and (x2, y2). 

So choose one of your points to be (x1, y1). Let's choose (4, -2). That means x1 = 4 and y1 = -2.
The other point would then be (x2, y2). So x2 = 24 and y2 = -17.

Now put these values in to the equation:
Slope = \frac{-17-(-2)}{24-4} =  \frac{-15}{20}  =  \frac{-3}{4}

The slope is -3/4.

A four pound duck, initially at a temperature of 50 degrees is place in an oven preheated to 375 degrees at 1:00. At 2:15 the du
jeyben [28]

1:00 to 2:15 is 1 hour and 15 minutes.

In that time the duck went from 50 to 125, which is a 75 degree increase.

75 degrees / 75 minutes = 1 degree per minute increase.

175 degrees - 125 degrees = 50 degree more it needs.

1 degree per minute  x 50 degrees = 50 more minutes.

50 minutes after 2:15, would be 3:05

It will be 175 degrees at 3:05

Triangle PQR has vertices P(–2, 6), Q(–8, 4), and R(1, –2). It is translated according to the rule (x, y) → (x – 2, y – 16).
Amanda [17]
Since you subtract 16 from the y value, P is (-2, 6), and the y value comes second (meaning that it's 6), we get 6-16=-10
