Answer:

x y

0 -1

-1 0

-8 7

Step-by-step explanation:

y = -x - 1

when x = 0, y = -1

when y = 0

0 = -x - 1

x = -1

when x = -8,

y = -(-8) - 1

y = 7

y = -x-1

1) y = -(0)-1

y = -1

2) 0 = -x-1

x = -1 + 0

3) y = -(-8)-1

y = 7

Hope this helps :)

What is the equation of a line that is parallel to −3x+4y=4 and passes through the point (4,0)?

Genrish500 [490]

So you have to first put put the equation in slope-intercept form.
-3x+4y=4
+3x +3x
_______________
4y=4+3x
then you divide 4 by 4 and then divide 3x by 4 and you should get y=1+3/4x
then you plug in x and only x so that you can find y and then do the same once you find y
y=1+ (4)3/4
y= 1+3
y=4
then plug in y and solve for x
4= 1+ 3/4x
subtract 1 from both sides
3=3/4x
divide both sides by 3/4
and x=4
so then you find b and put it all in a equation.

Please help me on math homework! File attached! :D

r-ruslan [8.4K]

Use pythagorena theorme

D= $\sqrt{(x1-x2)^{2}+(y1-y2)^{2}}$
NOTE: x1 and x2 means the first x and second x, not x^1 and x^2

points given are
(1,1)
(5,6)
x1=1
y1=1
x2=5
y2=6
D= $\sqrt{(1-5)^{2}+(1-6)^{2}}$
D= $\sqrt{(-4)^{2}+(-5)^{2}}$
D= $\sqrt{16+25}$
D= $\sqrt{41}$
6.403

answer is B
