You can use the distance formula
Sqroot((x2-x1)^2 + (y2-y1)^2)
(2,-1) and (5,3), use given points
Sqroot((5-2)^2 + (3-(-1))^2)
Sqroot((3)^2 + (4^2)
Sqroot(9+16) = squareroot of 25

Squareroot of 25 = 5

Solution: D. 5 units

Basile [38]

Answer:

y=3/2x+-1

Step-by-step explanation:

the formula is y=mx+b

y is the total

m is the slope

x is what you're multiplying the slope by

b is the y intercept

Which expression is equivalent to (sqrt3 + i)^3?

Anarel [89]

Express √3 + i in polar form:

|√3 + i| = √((√3)² + 1²) = √4 = 2

arg(√3 + i) = arctan(1/√3) = π/6

Then

√3 + i = 2 (cos(π/6) + i sin(π/6))

By DeMoivre's theorem,

(√3 + i)³ = (2 (cos(π/6) + i sin(π/6)))³

… = 2³ (cos(3 • π/6) + i sin(3 • π/6))

… = 8 (cos(π/2) + i sin(π/2))

… = 8i

Which equation represents a line which is parallel to the line y = -7/2x-3

Maksim231197 [3]

You do not have the options listed, but I will tell you what the line needs:

[] A parallel line will need the same slope.

- The slope is our m in y = mx + b

[] What will this be for our problem:

- $y=\frac{-7}{2}x-3$

- Our slope is $\frac{-7}{2}$

[] So what will the line look like:

- $y=\frac{-7}{2}x +?$

- Since you do not have the options listed, I cannot tell you the answer, but I can tell you the answer will have a slope of $\frac{-7}{2}$

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
