Which equation is the equation of the line in point slope form that has a slope of 1.8 and passes through the point (-4.5, 1.4)

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

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

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
