HELP PLEASE http://static.k12.com/calms_media/media/213000_213500/213123/1/7c34fa0e2dcd286d023240417eb68498aae2b193/VHS_ALG_S1_07_L203_L303_LQ4_graphi.gif Which line is a graph of the equation: –2x + 5y = 10?

Answer 1

a)
If we let y = 0, then -2x +5(0) = 10, so x = -5, and thus the x-intercept is -5.
If we let x = 0, then -2(0) + 5y = 10, so y = 2, and thus the y-intercept is 2.
From the graphs, we see that line a) has x-intercept -5 and y-intercept 2.

Answer 2

so its line a?

Answer 3

yep.
