Equation parallel to y = 3x + 2 and passing through (1, 1)
Kisachek [45]

Answer:

y = 3x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, then

y = 3x + c ← is the partial equation

To find c substitute (1, 1) into the partial equation

1 = 3 + c ⇒ c = 1 - 3 = - 2

y = 3x - 2 ← equation of line

For what values of x is the following equation satisfied : 3x+9 = 21+7x ?
olya-2409 [2.1K]
First of all, the first power of 'x' is the highest power in the whole equation,
so we only expect one solution.

You said that <span><u>3x+9 = 21+7x </u>

Subtract 3x from each side:

9 = 21 + 4x

Subtract 21 from each side:

-12 = 4x

Divide each side by 4 :

<u>-3 = x </u>
