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

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
