G(-4)

=1/2((-4)-1)

=1/2(-5)

=-2.5

------------------------------

f(g(-4))

=f(-2.5)

=2(-2.5)+1

=-5+1

=-4

Find the value of r so the line that passes through the pair of points has the given slope. (r, −5), (3, 13), m=8
Masteriza [31]

The value of r is found as 3/2 such that line that passes through the pair of points.

<h3>Describe the term slope of the line?</h3>
  • The ratio of both the altitude to that same horizontal distance (rise across run) between two places is typically used to calculate the slope, a numerical value that represents how steep a line is.
  • A line's slope provides information on the steepness and direction of the line.
  • By calculating the difference between coordinates of the two points, (x1,y1) and (x2,y2), it is simple to calculate the slope of either a straight line between them.
  • The letter "m" is frequently used to denote slope.

The slope is given bye the equation;

m = (y2 - y1)/(x2 - x1)

For the given question, the points are given as;

(x1, y1) = (r, -5),

(x2, y2) = (3, 13)

m = 8

8 = (13 + 5)/(3 - r)

8(3 - r) = 18

8r = 6

r = 3/2

Thus, the value of r is found as 3/2 such that line that passes through the pair of points.

The correct question is-

Find the value of r so the line that passes through each pair of points has the given slope. (r, -5), (3, 13), m = 8
