Here is my answer.. correct me if im wrong.
The equation is y = -3/2
this is because the line crosses zero on the Y axis so there is no Y intercept
and to get the slope you just see how many units down & then right you need to get from the center point to the one more down
Step-by-step explanation:
(t+4)(t+7)-54=0
t²+7t+4t+28-54=0
t²+11t-26=0
(t-2)(t+13)=0
t-2=0
t=2
t+13=0
t=-13
N/2=-12 multiply both sides by 2
n=-24
So the number is -24
