2.(-2,5)(-4,7)(-9,10)(-11,12)
3.(3,-5)(7,9)(2,3)(-5,9)
4.(4,7)(-2,5)(-2,6)(-5,10)
10 POINTS PLS HELP!

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
