Question

I really need help with this stuff but please explain, no direct answers

write and equation in standard form

the line has the same slope as 5x-y=7 and the same y-intercept as the graph of 2y-7x=8.

the equation in standard form is?

Answer 1

eqn of a straight line in standard form is

y = mx + c;

where m is the slope and c is the y-intercept.

So far so good?

Answer 2

ok

Answer 3

"he line has the same slope as 5x-y=7 "

so we need to find out the slope from 5x-y=7....

can u put 5x-y=7 into the standard form of y=mx+c plz?

Answer 4

y=-5x+7

Answer 5

are you there?

Answer 6

Ooops sorry I got distracted....almost right but it should be

y=5x-7

see where u made the mistake?

Answer 7

yes

Answer 8

So what is the slope? We need that for part of the ans :)

Answer 9

5

Answer 10

Correct! So keep that in mind and we work on finding the y-intercept ok?

Answer 11

"(T)he same y-intercept as the graph of 2y-7x=8"

-same deal: put 2y-7x=8 into standard from y=mx+c to find the y-intercept

Answer 12

2y=7x+8

y=7/2x+4

Answer 13

GREAT job! :) so whats the y-intercept here?

Answer 14

4

Answer 15

Combining that w slope of 5, ur ans in standard form eqn is....

Answer 16

y=5x+4?

Answer 17

is that right?

Answer 18

Bingo - u got it :)

Answer 19

thank you sooo much!

Answer 20

welcome! U did most of the work urself! lol
