Write the equation of the line passing through the points (−1, 2) and (3, 4)



A)y = 2x − 2B)y = 2x − 10C)y = 12x + 52D)y = 12x − 52

y = x +

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m =

with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (3, 4)

m = = = , thus

y = x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation.

Using (3, 4), then

4 = + c ⇒ c = 4 - =

y = x + ← equation of line

ab will be equal to

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
