)

Answer:

2/3

Step-by-step explanation:

To find slope the formula is (y2-y1)/(x2-x1).

Using that we substitute the pairs.

(-4,-1), (2,3) would then be (x1, y1), (x2, y2)

so you solve from there.

the equation would be ( 3 - ( - 1 ) ) / ( 2 - ( - 4 ).

( 3 - ( - 1 ) ) / ( 2 - ( - 4 )

( 3 + 1 ) / ( 2 + 4 )

4 / 6

2 / 3

Plz don’t be rude if i got brainly i’m gonna use it
SSSSS [86.1K]

Answer:

y=-5x-36

Step-by-step explanation:

-66-(-61)= -5

6-5= 1

-5/1= -5

Y=-5x + B

-66= -5(6) + B

-66= -30 + B

-66 + 30 = (-30 +30) + B

-36 = B

Y= -5x-36

the line whose equation is y=1/2x-3 is dilated by a factor of 3 with a center at the point (10,2). Explain why its equation woul
lana [24]
We  have that

<span>y=1/2x-3
1) the slope of this line equation is m=(1/2)
2) the coordinates of the y intercept are
for x=0
y=-3
point (0,-3)
3)</span>the coordinates of the x intercept are
for y=0
0=(1/2)x-3------> (1/2)x=3----> x=6
point (6,0)

<span>if the line is dilated by a factor of 3
then
</span>y=1/2x-3--------> 3y=3*[1/2x-3]-----> 3y=(3/2)x-9
3y=(3x-18)/2-------> y=(3x-18)/6--------> y=(3/6)x-18/6

 y=(3/6)x-18/6
so
1) the slope of this line equation is m=(3/6)-----> 3/6=1/2
2) the coordinates of the y intercept are
for x=0
y=-18/6-------> y=-3
point (0,-3)
3)the coordinates of the x intercept are
for y=0
0=(3/6)x-18/6------> (3/6)x=18/6----> x=18/3------> x=6
point (6,0)

therefore
the equation of the line
y=1/2x-3 is the same that the equation of the line  y=(3/6)x-18/6

<span>the equation does not change because the slope and the x and y intercepts do not change either</span>
