y = 3x - 7 / 7

answer:

any vertical line is parallel to the y-axis in a co-ordinate plane.

therefore the angle of inclination is equal to 90 degrees.

according to the formula , slope of a line = tan θ

step-by-step explanation:

687.09 dollars       happy now

step-by-step explanation: 6870

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

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
