This is just to easy the correct answer is A
First of all, you have to calculate slope of that,
m = (y2-y1)/(x2-x1) = (1-0)/(0+2) = 1/2
now, equation would be y-y1 = m(x-x1)
y-1 = 1/2(x-0)
y-1 = x/2
y = x/2+ 1

Answer:
Step-by-step explanation:
1 m is 100 cm, so the volume is ...
V = LWH
V = (100 cm)(50 cm)(4 cm) = 20,000 cm³ . . . volume
__
The mass is ...
(20,000 cm³)(2.7 g/cm³) = 54,000 g = 54 kg
The mass of the block is 54 kg.
The standard form for this parabola is x = a(y-k)^2 + h because this is a sideways-opening parabola. Our h and k values for the vertex are (-4, -1). And it goes through (2,0). We just need to solve for the a. Filling in accordingly, 2 = a(0+1)^2-4 so 2 = a - 4. a = 6. A above.
correct answer is 6!
