Answer:

60 and 38

Step-by-step explanation:

let the two numbers be X and Y

X + Y = 98-----------(1 )

X - Y = 22-----------(2)

using elimination method, subtracting equation (1) from equation (2)

X - X = 0

+Y -(-Y) = Y + Y = 2Y

98 -22 = 76

2Y = 76

dividing bothsides by 2

2Y/2 = 76/2

Y = 38

substitute Y = 38 into equation (1)

X + 38 = 98

X = 98-38 = 60

therefore, the two numbers are 60 and 38

Find the slope of the line. On a coordinate plane, a line goes through (0, negative 6) and (2, 0). a. Negative one-third c. 3 b.
statuscvo [17]

The slope of the line that passes through between (0, -6) and (2, 0) is: C. 3.

<h3>What is the Slope of a Line?</h3>

The slope of a line can be defined as the measure of the ratio of the vertical distance to the horizontal distance that exists between two points on a coordinate plane.

<h3>How to Find the Slope of a Line?</h3>

If we are given two points on a line, (x1, y1) and (x2, y2), the slope (m) is the rise/run = change in y / change in x = (y2 - y1)/(x2 - x1).

Given the following coordinates of two points as follows, (0, -6) and (2, 0), let:

(0, -6) = (x1, y1)

(2, 0) = (x2, y2)

Plug in the values into the slope formula to find the slope:

Slope (m) = (0 - (-6)) / (2 - 0)

Slope (m) = (0 + 6) / (2 - 0) [minus multiplied by minus is plus]

Slope (m) = (6) / (2)

Slope (m) = 3

Thus, the slope of the line that passes through between (0, negative 6) and (2, 0) is calculated as: C. 3.
