OpenStudy (studygurl14):

line goes down from left to right, thus a negative slope. line intersects y-axis at -2, so y-intercept is -2.

OpenStudy (jamaljunior):

so therefore it cant be C?

OpenStudy (studygurl14):

y = mx + b Based on what I told you, m must be negative, b = -2

OpenStudy (studygurl14):

only one answer choice fits that

OpenStudy (jamaljunior):

A?

OpenStudy (jamaljunior):

OpenStudy (jamaljunior):

Using points (-1,2) and (0,-2) from the graph, I cranked out the equation of the line and agree with your choice of >>>oh its D

OpenStudy (jamaljunior):
