12 is B. You because the graphs slope is 1. 13 is A 7 I think.
A. (0,-6)
plug in the area to the area formula for a triangle (A=1/2bh). so 28=1/2b(4) [since the height is 4]. divide by 4 (7=1/2b). multiply by 2/divide by 1/2 (14=b). the base equals 14 units long.
B. y=2/3x+4
find the slope of the line (2/3)
the y-intercept is 4
Answer:
no one can answer this question since it doesn't show the choices, but if whichever one is 90 degrees/ has a little square in the corner would be the right answer
It is necessary to include the term one then you will have the plus three
We do not see a graph above
