Answer:

x = 1.75 -y, y = 1.25 + x

Step-by-step explanation:

Part One

2x + y = 3.5

<em>Divide</em>

x + y = 1.75

<em>Move the variable and change its sign</em>

x = 1.75 -y

Part Two

-x + 2y = 2.5

<em>Divide</em>

-x + y = 1.25

<em>Add</em>

y = 1.25 + x

Write the equation for the line in slope intercept form ​
Helen [10]

Answer:

  y = -2x -3

Step-by-step explanation:

The line crosses the y-axis at -3, so that is the y-intercept.

It has a "rise" of -2 units for each "run" of 1 unit, so the slope is -2. (For example, from point (-1, -1) to point (0, -3).)

The slope m and y-intercept b are used in the slope-intercept form of the equation of a line:

   y = mx + b

For the values this line has, the equation is ...

   y = -2x -3
