Answer:

x = 46°

Step-by-step explanation:

2x - 30 + 2x - 30 + x + 10 = 180°

combine like terms:

5x - 50 = 180°

5x = 230°

x = 46°

Y=1/4x + 6<br> that passes through the point (-4, 3) in slope-intercept form.
Komok [63]

Answer:

The answer is

<h2>y =  \frac{1}{4} x + 4</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line.

The equation is

y = 1/4x + 6

Comparing with the general equation above

Slope = 1/4

Since the lines are parallel their slope are also the same

That's

Slope of parallel line = 1/4

So the equation of the parallel line using point (-4 , 3) and slope 1/4 is

<h3>y - 3 =  \frac{1}{4} (x + 4) \\ y - 3 =  \frac{1}{4} x + 1 \\ y =  \frac{1}{4} x + 1 + 3</h3>

We have the final answer as

<h3>y =  \frac{1}{4} x + 4</h3>

Hope this helps you
