Find EF given E(-7, -2) and F(11, 3). Round your answer to the nearest thousandth (3 decimal places).
zavuch27 [327]

Answer:

18.682

Step-by-step explanation:

Given that :

E = (-7, - 2) ; x1 = - 7 ; y1 = - 2

F = (11, 3) ; x2 = 11 ; y2 = 3

EF = √((x2 - x1)² + (y2 - y1)²)

EF = √((11 - -7)² + (3 - -2)²)

EF = √((11 + 7)² + (3 + 2)²)

EF = √(18² + 5²)

EF = √324 + 25

EF = √349

EF = 18.6815

EF = 18.682 units (3 decimal places )

Find the slope of each line.<br><br> Y= -5/2x — 5
Dmitriy789 [7]
To find the slope of the line, simply remember the basic equation for the slope intercept.

Y = mx +/- b

Where m = slope or rise/run
b = y intercept.

In this case the slope is a negative value and is -5/2.
