The two figures that multiply to-48 and add up to-2 are-8 and 6.
Let's assume the two figures are x and y.
According to the problem, we've two conditions
x y = -48
x y = -2
To break this, we can rewrite the alternate equation as
x = -2- y
Now substitute this value of x in the first equation
(-2 - y) y = -48
- 2y- y² = -48
Rearranging the terms
y² + 2y- 48 = 0
Now, solving the Quadratic Equation
(y+ 8)( y- 6) = 0
Setting each factor to zero
y + 8 = 0--> y = -8
y- 6 = 0--> y = 6
So we've two possible values for y is -8 and 6.
Substituting these values back into the equation x + y = -2, we can break for x
For y = -8
x(- 8) = -2
x- 8 = -2
x = 6
For y = 6
x 6 = -2
x = -2- 6
x = -8
Thus, the two figures that multiply to-48 and add up to-2 are-8 and 6.

Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 1.67
Draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 1.67
Answer:
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6
Step-by-step explanation:
Data
x: total minutes used
y: total monthly charges
x | y
100 | $135
500 | $375
That can be expressed as coordinates (x, y), so the points are (100, 135) and (500, 375).
The slope is computed with two points (x2, y2) and (x1, y1) as follows:
slope = (y2 - y1)/(x2 - x1)
Replacing with data
slope = (375 - 135)/(500 - 100) = 0.6
