<span>Let's take a look at the available steps and see what makes sense. "Construct a point at one of the two intersection points of circle E and circle F and label this point G" ** We don't have anything drawn yet, so this step goes later. "Construct EG¯¯¯¯¯ ​ and FG¯¯¯¯¯​" ** Same issue, nothing done yet. But this looks like it would be the last step. "Construct ​ EF¯¯¯¯¯​" ** OK. We can draw a line and label the end points E and F. So make this step 1. "Construct a circle with point E as the center and a circle with point F as the center with each circle having radius EF" ** This looks like it would also work for step 2, since we've already constructed the line segment EF. So the entire process looks like: 1. Construct ​ EF¯¯¯¯¯​ 2. Construct a circle with point E as the center and a circle with point F as the center with each circle having radius EF . 3. Construct a point at one of the two intersection points of circle E and circle F and label this point G. 4. Construct EG¯¯¯¯¯ ​ and FG¯¯¯¯¯​.</span>

Find the equation of the line that passes through (4,4) and is parallel to
Black_prince [1.1K]

Answer:

y = - 3x + 5

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 )

Given

3x + y + 2 = 0 ( subtract 3x + 2 from both sides )

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

with slope m = - 3

Parallel lines have equal slopes, thus

y = - 3x + c ← is the partial equation

To find c substitute (3, - 4) into the partial equation

- 4 = - 9 + c ⇒ c = - 4 + 9 = 5

y = - 3x + 5 ← equation of line in form y = mx + c
