Simplify 7x + 2y = -23
Solving
7x + 2y = -23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
7x + 2y + -2y = -23 + -2y
Combine like terms: 2y + -2y = 0
7x + 0 = -23 + -2y
7x = -23 + -2y
Divide each side by '7'.
x = -3.285714286 + -0.2857142857y
Simplifying
x = -3.285714286 + -0.2857142857y

Answer:
The value of the slope is 6
Step-by-step explanation:
To get the slope of the line, we are going to make use of the slope equation
Mathematically, we have this as;
m = (y2-y1)/(x2-x1)
where (x1,y1) = (1,2) and (x2,y2) = (2,8)
Substituting these values;
m = (8-2)/(2-1) = 6/1 = 6
