Question

What is the slope and y interception of the line 4x+7y=21
(Need to show work)

Answer 1

Hello @erik101 and Welcome to OpenStudy! :)

it would be easier to identify the slope and y-intercept if we had the equation in the slope intercept form
y = mx + b

so let's first try to get y alone on one side

subtract 4x from both sides
then divide both sides by 7

can you do that? :)

Answer 2

Okay I got y=-4x+3

Answer 3

close! :D

y = (-4/7) x + 3 then we have
y = m x + b as the formula
where m = slope and b = y-intercept

Answer 4

slope -4/7x and y-intercept= 3?

Answer 5

slope is the number without that x
so slope = -4/7

but yes, that's correct! :)
