So first you need to get the y by itself so subtract 4x to the on both sides to move it on the other side of the equal symbol and then divide -2 to the whole equation to get y by itself and you’ll get this: y=2x-1
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)
