Susie determined that the system of equations below has infinitely many solutions. *Use your graphing calculator! The first line goes through the points (2, -13) and (-2, -1) The second line goes through the points (5, -22) and (-3, 2) (1 point) Responses Yes, Susie is correct. Yes, Susie is correct. No, there is one point of intersection No, there is one point of intersection No, the lines are parallel No, the lines are parallel She may or may not be correct as the lines possibly cross
No, there is one point of intersection.
well, just for sport
slope of first one = 12/-4 = - 3
so
y = -3 x + b
-1 = -3(-2) + b
b -7
y = -3 x - 7
and second one
slope = 24/-8 = -3 AGAIN
same slope
y = -3 x + b
put in (-3,2)
2 = -3 *-3 + b
b = -7
so y = -3 x - 7
same slope, different intercepts, parallel, no solution
