|\Omega|=6^2=36\\ |A|=\underbrace{3\cdot3}_{\text{O,O}}+\underbrace{3\cdot3}_{\text{E,E}}=18\\\\ P(A)=\dfrac{18}{36}=\dfrac{1}{2}=50\%

Please help me ASAP
Colt1911 [192]
First,let's find the slope-intercept form of equation which is y=mx+b, where y and x are coordinates, m is the slope and ,c is the y-intercept
y+6.75=0.25(x-1)                                                   y=0.25(2)-6.5
y+6.75-6.75=0.25x -0.25 -6.75                            y=-6
y=0.25x-6.5   
(2,-6)  is the only correct answer I think is on the line with this equation.
