The value of x in the algebraic expression is -2.5
<h3>What is an algebraic expression?</h3>
An algebraic expression is the representation of numbers with variables with the purpose of solving for the variable. The variables are expressed by using alphabetical letters, here it is (x).
From the given algebraic expression, we have:
4x + 2 = -8
Collect like terms
4x = -8 - 2
4x = - 10
Divide both sides by 4
x = -2.5

Answer: The value of a is -6.
Step-by-step explanation:
To do this we need to find the y-intercept first.
-2= 4(1/2) + b
-2=2+ b
-2 -2
b= -4 so now the y-intercept is -4 so we will now have the equation y= 1/2x -4
so now put -4 into the equation for x and solve for y.
y= 1/2(-4) -4
y = -6
