What is the slope and y-intercept of the equation represented by the following graph?
A. slope = 2, y-intercept = -1/2 B. slope = -2, y-intercept = -1/2 C. slope = -1/2 , y-intercept = 2 D. slope = 1/2 , y-intercept = 2 E. slope = -1, y-intercept = 2
y intercept = where does the line cross the y axis? @AnonymousBella
y intercept = where does the diagonal line cross the y axis? @AnonymousBella ?
2
yep
slope = rise over run so going from left to right, is the line "uphill" or "downhill" ?
downhill?
yep, so the slope will be a negative number, as it's "downhill"
so not A, (wrong y intercept) not B, (wrong y intercept) not D (wrong slope) must be C or E
C?
slope = rise over run =(y2 - y1)/(x2-x1)

|dw:1385116249160:dw| can you solve from here? @AnonymousBella ? using \[\huge slope = \frac { y_2 - y_1}{ x_2 - x_1}\]
