Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (1, 0) , thus
y = a(x - 1)² + 0
To find a substitute the coordinates of the y- intercept (0, 1) into the equation
1 = a(- 1)² = a , thus
a = 1
y = (x - 1)² → A
Answer:
i)vertical
ii)horizontal
iii)oblique
Step-by-step explanation:
When an equation is just x=a number, it is a horizontal line.
When the equation is just y=a number, it is a vertical line.
If the equation is the full y=mx+b, it is oblique.
2x=5
x=2.5
vertical
y+2=-1
y=-3
horizontal
x+y=3
y=-x+3
oblique
:) ur welcome
Answer:
No
Step-by-step explanation:
5 × 6 = 30 - 5 = 25
5 × 2 = 10 - 1 = 9
