The point-slope form of the equation of a straight line is:

We have:

Substitute:

Answer:
x = -14
Step-by-step explanation:
Let's solve your equation step-by-step.
4x + 188 = 6x +216
Subtract 6x from both sides:
4x + 188 - 6x = 6x + 216 - 6x
-2x + 188 = 216
Subtract 188 from both sides:
-2x + 188 - 188 = 216 - 188
-2x = 28
Divide both sides by two:


167.0067

= 
in this case its
+
= 
25 +
= 169 subtract 25 from both sides
= 144 take square root of each side
b = 12
