Y - 190 = 55(x - 2)....distribute thru the parenthesis
y - 190 = 55x - 110....now add 190 to both sides
y = 55x - 110 + 190..simplify
y = 55x + 80 <== slope intercept form (y = mx + b)

Answer:

<em>The equation in slope-intercept form will be:  y=55x+80</em>

Step-by-step explanation:

The given equation is:   y-190=55(x-2)

The standard slope-intercept form is  y=mx+b

Simplifying the given equation..........

y-190=55(x-2)\\ \\ y-190=55x-110\ \ \ [using\ distributive\ property\ in\ right\ side]\\ \\ y-190+190=55x-110+190 \ \ \ [adding\ 190\ both\ sides]\\ \\ y=55x+80\ \ \ [combining\ like\ terms]

<em>This equation is in form of y=mx+b</em>

So, the equation in slope-intercept form will be:  y=55x+80

6x + 8 = 50 solve equation
shepuryov [24]
6x + 8 = 50

Our goal is to get the variable x on its own.
We can start by subtracting 8 from each side. (subtraction prop. of eq. lets us do this)

6x + 8 - 8 = 50 - 8
6x = 42

Now, we must divide each side by 6 to find the value of x.

6x ÷ 6 = 42 ÷ 6
x = 7
