Question

STOP AND HELP PLEASE!
Which equation represents the line passing through the points (1, 4) and (-2, 13)?
x - 3y = 7
3x - y = 7
x + 3y = 7
3x + y = 7

Answer 1

What is the slope of a line that passes through the point (-1, 1) and is parallel to a line that passes through (4, 6) and (-1, -4)? Help with this as well plz?

Answer 2

for the line to pass through the points(1,4) and (-2,13). that the equation has to verify x and y as solution that mean if you replace them in the equation it should work and regarding that only the last equation: 3x+y=7 is correct. because when you replace x=1 and y=4 it works and so for x=-2 and y=13

Answer 3

okay thanks can you do the other one?

Answer 4

sure hold on

Answer 5

thanks soooooooooooo much been working 3 hours on this study guide!

Answer 6

two line parallel means they have the same slope so you can use the two points to find the equation of the other line which is going to be y=2x-2 therefore the slope is 2 and its gonna be the same slope as the other line so your answer is: slope=2

Answer 7

thanks soo much!
