Select the equation in which the graph of the line has a positive slope, and the y-intercept equals -8.

Question 1 options:

5x + y = 50


5x - 10y = -12


x - 2y = 10


10x - 5y = 40

first step: which have positive slopes?
Answered by Jay
a , c and d @steve
Answered by Steve
no, (a) has a negative slope. Rearrange things into slope-intercept form and you get

5x + y = 50
y = -5x+50
slope = -5, intercept=50

do that for the others, and it will then be clear which is what you want.
