Question 1087700: If 2 points on a line have coordinates (0,A) and( 2, -3) and the slope of the line is A, then what is the value of A?
note: (0,A) is the y intercept.
Thanks so much. This was an SAT practice problem.

y=Ax%2BA according to, "(0,A) is the y intercept" and "slope of the line is A".


%28-3-A%29%2F%282-0%29=A, definition of slope of a line, and "2 points on a line have coordinates (0,A) and( 2, -3) and the slope of the line is A";
-
-3-A=2A
-3=3A
-3%2F3=A
A=-1-------solved for slope, A.

Equation for the line: highlight%28y=-x%2B1%29
