Question

help

Answer 1

firstly, if two lines are parallel, they have the same slope

Answer 2

so which two choices can you eliminate?

Answer 3

this fat cat says C

Answer 4

you can eliminate another too

Answer 5

this fat cat says B

Answer 6

nope

Answer 7

the slope has to be -3

Answer 8

This fat cat does not understand this

Answer 9

y = mx + b
where m is the slope

Answer 10

the equation y = -3x + 7 means that the slope is negative 3 and the y-intercept is 7

Answer 11

this fat cat says he sees no slope

Answer 12

parallel lines have the same slope

the slope of y= -3x + 7 is -3

the slope of y = 3x + 14 is 3
the slope of y = -3x + 2 is -3
the slope of y =1/3 x + 4 2/3 is 1/3
the slope of y= -3x + 10 is -3

so which equations have a slope of -3...

Answer 13

This fat cat says B

Answer 14

This fat cat says also D

Answer 15

Yeah so slope is -3

Now we have to find the y-intercept using the slope and the coordinate point
substitute the x y values into the equation
(2,-4)
y=mx+ b
-4 = -3(2) + b

can you solve for b?

Answer 16

no

Answer 17

what is -3 times 2

Answer 18

-6?

Answer 19

yes so
-4 = -6 + b

what is -4 plus 6

Answer 20

2?

Answer 21

yes the b is 2

the equation is y = -3x + 2

Answer 22

b is correcto?

Answer 23

si

Answer 24

gracias c;

Answer 25

de nada
