The vertex point is (0,4)
The two other points are (-2,0)(2,0)
Answer:
Step-by-step explanation:
BC=AD
3x-1=x+5
3x-x=5+1
2x=6
x=3
BC=3×3-1=8
CD=2x=2×3=6
perimeter=2(8+6)=2(14)=28
Answer:
y-intercept
Step-by-step explanation:
The intercept is not a point, it is only the value at which the line crosses
