Write an equation in slope-intercept form for the line that passes through (−2, 3) and is parallel to
the line with the equation 3x + 2y = 6.

Answers

y= (-3x+6)2

For parallel lines, slopes are the same,

y = mx + c

Substitute the values,

3 = (-3/2)(-2) + c

3=3 + c,

c = 0

Thus, the equation is y= -3/2x

How do you solve
8.4-6.8=-3.2y+16.4

Answers

Answer:

  y = 4.625

Step-by-step explanation:

Subtract 16.4 from both sides and collect terms.

  8.4 -6.8 -16.4 = -3.2y +16.4 -16.4

  -14.8 = -3.2y

Divide both sides by -3.2.

  -14.8/-3.2 = (-3.2y)/-3.2

  4.625 = y

The solution is y = 4.625.

Answer:

y=4.625
