work out the equation of the line which passes through the point (-1, 2) and is parallel to the line y=x+4

Sauron [17]

The equation of the line which passes through the point (-1, 2) and is parallel to the line y = x + 4 is y = x + 3

<h3>Solution:</h3>

Gtiven that line passes through the point (-1, 2) and parallel to line y = x + 4

We have to find the equation of line

The equation of line in slope intercept form is given as:

y = mx + c ---------- eqn 1

where "m" is the slope of line and "c" is the y - intercept

Let us first find the slope of line

Given equation of line is y = x + 4

On comparing the given equation of line y = x + 4 with general slope intercept form y = mx + c,

we get slope of line "m" = 1

We know that slopes of parallel lines are equal

So the slope of line parallel to line having equation y = x + 4 is also 1

Now we have to find the equation of line having slope "m" = 1 and passes through point (-1, 2)

Substitute m = 1 and (x, y) = (-1, 2) in eqn 1

2 = 1(-1) + c

2 = -1 + c

c = 3

Thus the required equation of line is:

Substitute c = 3 and m = 1 in eqn 1

y = 1x + 3

y = x + 3

Thus the required equation of line is found out

Elsie bought 3.00 pounds of pecans for $9.60. Her friend buys 4.50 pounds of walnuts for $15.75. Which is more expensive per pou

natali 33 [55]

Divide 9.60 by 3, and 15.75 by 4.50
The bigger number will be the most expensive and subtract the bigger quotient by the smaller and you’ll get the difference.

Which of the following are the solutions to |5x + 2|=8

lukranit [14]

Hi there!

Let's solve this equation step by step!
$|5x + 2| = 8$

First work out the absolute value, which makes everything between the stripes positive. When we have a negative outcome between the stripes (for instance -8), the stripes make it positive. When we work out the absolute value, we mustn't forget this solution.

$5x + 2 = 8 \: \: or \: \: 5x + 2 = - 8$
Subtract 2

$5x = 6 \: \: or \: \: 5x = - 10$
Divide both sides by 5.

$x = \frac{ 6}{5} = 1 \frac{1}{5}\: \: or \: \: x = -2$
~ Hope this helps you!

The images showed a right angle along with a 20° angle. As you should already know a right angle = 90°

So,

90° + 20°
