Find the equation of the line that passes through the points 2,5 and -8,4

Mathematics
1 answer:
n200080 [17]3 years ago
4 0

Answer:

y = 1/10 x  + 24/5

or in standard form this is

-x + 10y = 48.

Step-by-step explanation:

The slope of the line is (5-4)/(2--8)

= 1/10

Using the point slope form y - y1 = m(x - x1):

USING THE POINT (2, 5):

y - 5 = 1/10(x - 2)

y - 5 = 1/10 x - 1/5

y = 1/10 x  + 24/5

A car travels at an average speed of 64 miles per hour. how many miles does it travel in 3 hours and 45 minutes
ELEN [110]
64*3= 192 I multiplied that because the car traveled for 3 hours at the speed of 64 miles.
64-15= 49 I subtracted 15 out of 64 because the car only traveled 45 minutes after the three hours.

Center: (-2,5), radius:7
Firlakuza [10]

Answer:

(x + 2)² + (y - 5)² = 7²

Step-by-step explanation:

Incomplete question.  I believe you meant, "write the equation of the circle with center at (-2, 5) and radius 7.

That would be:

(x + 2)² + (y - 5)² = 7²

Help on 22 and 23 please
hram777 [196]

Answer:

22.

R= -8, 15

S= -5, 9

T= -8,9

23.

J = 4, 4

K = 4, 3

L = 1, 1

M = 1, 4

Step-by-step explanation:

rotation of -90= y, -x

so R (-7, -5) = -5,7

S (-1, -2) = -2, 1

T (-1, -5) = -5, 1

now we translate 3 left (x-3) and 8 up (y+8)

R (-5, 7) = -8, 15

S (-2, 1) = -5, 9

T (-5, 1) = -8, 9

reflection of x-axis= x, -y

J (-4, 4) = -4, -4

K (-3, 4) = -3, -4

L (-1, 1) = -1, -1

M (-4, 1) = -4, -1

Then a 180° rotation is (-y, -x)

J (-4, -4) = 4, 4

K (-3, -4) = 4, 3

L (-1, -1) = 1, 1

M (-4, -1) = 1, 4
