What is the equation of the line that passes through (3.-1) and is parallel to the line y = 3x + 2?​

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

From the given line, we can identify clearly that 3 is in the place of m, making it the slope. Because parallel lines have the same slope, the line we're solving for will also have a slope of 3. Plug this into :

2) Determine the y-intercept (b)

Plug in the given point (3,-1)

Subtract 9 from both sides

Therefore, the y-intercept of the line is -10. Plug this back into :

I hope this helps!

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
