The value of x in this system of equations is 1. 3x + y = 9
y = - 4x + 10
1. Substitute the value of y in the first equation:
2. Combine like terms:
3. Apply the subtraction property of equality:
4. Apply the division property of equality:
3x + ( 4x + 10) = 9
-x+ 10 ='9
-X-1
X = 1
What is the value of y?
y =
Done
Intro

y = -x - 2

Step-by-step explanation:

Simplifying the equation of our line;

y - 1 = (x + 2)

y = x + 3

The slope of our line is 1

The slope of the perpendicular line(s) must be -1 (the product of slopes of two perpendicular lines = -1)

The line whose slope is -1 (from the choices) is the one whose equation is:

y = -x - 2
