Question

Answer Check - What is the slope and y-intercept: 4x + 7y = 28? My answers are in the comments.

Answer 1

y = 4, x = 7
y-intercept = (0, 4)
Slope = 7/3

Answer 2

@Sadworld r u there?

Answer 3

here

Answer 4

oh okay the y-intercept is correct but how did u get the slope?

Answer 5

\[\frac{ y_2 - y_1 }{ x_2 - x_1 }; (x_1, y_1) = (7, 0); (x_2, y_2) = (0, 4)\]

Answer 6

I think I got it backwards...?

Answer 7

idk lol but i think solving for y would be easier \[4x+7y=28 \]
\[7y=-4x+28 \]
\[y=-4/7x +4 \]

Answer 8

Damn, didn't saw that one... thanks.

Answer 9

lol it happens :P np
