Answer:
2
Step-by-step explanation:
Variance = square of standard deviation
Variance = (2.5)^2 = 6.25 = 6.3 to the nearest tenth.
You left off the choices but we don't need them.
The point slope form, a line with slope m through (a,b), is
y - b = m(x-a)
We have m=1.8 and (a,b)=(-4.5,1.4) so
Answer: y - 1.4 = 1.8(x + 4.5)
You'll have to find that one among the choices yourself.
We solve for y to get the slope intercept form
y = mx + (b - ma)
Here we have m=1.8 and (a,b)=(-4.5,1.4) so
y = 1.8x + (1.4 - 1.8(-4.5))
y = 1.8x + 9.5
1.00
1.25
would be your two answers
