Answer:
C. 4, D. 2, A. -1
Step-by-step explanation:
On the graph, the points at 0 are 4, 2, and -1.
parallel lines have the same exact slope hmmm what's the slope of y = 2/3x-7 anyway? well, low and behold, is already in slope-intercept form, therefore
.
so we're really looking for the equation of a line whose slope is 2/3, and runs through 3, -1.
