Answer:y = -7, x = 12

Step-by-step explanation:

y + x = 5

x = 5 - y

y = 2(5 - y) + 11

y = 10 - 2y +11

-y -y

0 = 10 - 3y + 11

21 = -3y

y = -7

-7 + x = 5

x = 12

Calculate the gradient of the line using rise/run method.
Lapatulllka [165]

Given:

The graph of line.

To find:

The gradient of the line using rise/run method.

Solution:

We know that the gradient of a line is also known as slope.

Slope=\dfrac{Rise}{Run}

Consider the two intercepts, then rise is distance between origin and y-intercept and run is the distance between origin and the x-intercept. But rise must be negative because the value of y decreased from 3 to 0.

Rise=-3

Run=2

Now,

Slope=\dfrac{Rise}{Run}

Slope=\dfrac{-3}{2}

The gradient of the line is -\dfrac{3}{2}.

Therefore, the correct option is C.
