math help!!! Which of the following has a slope of –3 and a y-intercept of –4? y = –3x + 4 y = 3x + 4 y = 3x – 4 y = –3x – 4

OpenStudy (anonymous):

they are in slope-intercept form which is y=mx+b m=the slope of the graph b= the y-intercept of the graph

OpenStudy (anonymous):

you can prove to yourself that b is the y-intercept by subbing in x=0 because the y-intercept will occur when x equals 0!
