Answer:

$\frac{1}{2}$

Step-by-step explanation:

Use the Slope Formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Using the points (2,3) and (-2,1).

$m=\frac{1-3}{-2-2}=\frac{-2}{-4}=\frac{1}{2}$

The slope of the line is $\frac{1}{2}$ .

Solve the system using elimination.

Shalnov [3]

Answer:

After simplifying we get (x,y) as (1,3).

Step-by-step explanation:

Given:

$x+7y=22$ ,

$x-7y=-17$

We need to use elimination method to solve the and simplify the equations.

Solution;

Let $x+7y=22$ ⇒ equation 1

Also Let $4x-7y=-17$ ⇒ equation 2

Now by solving the equation we get;

first we will Add equation 2 from equation 1 we get;

$(x+7y)+(4x-7y)=22+(-17)\\\\x+7y+4x-7y=22-17\\\\5x=5$

Now Dividing both side by 5 using division property of equality we get;

$\frac{5x}{5}=\frac{5}{5}\\\\x=1$

Now Substituting the vale of x in equation 1 we get;

$x+7y=22\\\\1+7y=22$

subtracting both side by 1 using subtraction property of equality we get;

$1+7y-1=22-1\\\\7y=21$

Now Dividing both side by 7 using division property of equality we get;

$\frac{7y}{7}=\frac{21}{7}\\\\y=3$

Hence we can say that, After simplifying we get (x,y) as (1,3).

Answer:

(6,4)

Step-by-step explanation:

y = x-2

y =4

Set the two equations equal

x-2 =4

Add 2 to each side

x-2+2 = 4+2

x =6

Now we need to find y

y =4

(6,4)

X^2+15x=-45 solve by factoring

Julli [10]

1 Move all terms to one side.

{x}^{2}+15x+45=0

+15x+45=0

2 Use the Quadratic Formula.

x=\frac{-15+3\sqrt{5}}{2},\frac{-15-3\sqrt{5}}{2}

A line is parallel to y = 2x - 8 and

Bad White [126]

Parallel line means having the SAME slope

so the slope of a line parallel to the given line is 2

plug in the given point and slope of 2 into point slope form
y+1 = 2 (x+4)

solve for slope intercept form
y+1 = 2x + 8
y = 2x + 7

answer: y=2x+7
