Write an equation for the line in slope intercept form to parallel to -x + 3y =-2 that contains the point (12,7)

The parallel lines have the same slope.

The slope-intercept form:

m - slope

b - y-intercept

We have

Therefore searched line equation is:

The line passes through point (12, 7). Put the coordinates of the point into the equation of the line:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
