6. Find the equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel
prisoha [69]
<h3><u>The equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel  to the line -5x + 4y = 8 is:</u></h3>

y = \frac{5}{4}x + 13

<em><u>Solution:</u></em>

Given that,

We have to find the equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel  to the line -5x + 4y = 8

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c

Where "m" is the slope of line

From given,

-5x + 4y = 8

Rearrange to slope intercept form

4y = 5x + 8

y = \frac{5x}{4} + \frac{8}{4}\\\\y = \frac{5x}{4} + 2

On comparing the above equation with slope intercept form,

m = \frac{5}{4}

We know that, slopes of parallel lines are equal

Therefore, slope of line parallel  to the line -5x + 4y = 8 is:

m = \frac{5}{4}

\text{Substitute } m = \frac{5}{4}\ and\ (x, y) = (-8, 3) \text{ in eqn 1}

3 = \frac{5}{4} \times -8 + c\\\\3 = -10 + c\\\\c = 13

Substitute c = 13 and m = 5/4 in eqn 1

y = \frac{5}{4}x + 13

Thus the equation of line in slope intercept form is found

Which scenarios have a posItive correlation. MARK ALL THAT APPLY. *
Anit [1.1K]

Answer:

Step-by-step explanation:

well the negative correlations are the number of calories consumed and the amount of weight lost by a person and the thickness of the ice on a lake and the likelihood of falling through the ice.

Negative correlation is defined as an inverse relationship between two entities. If entity 1 increases, entity 2 decreases and if entity 2 increases, then entity 1 decreases.

So the postive are

the temperature outside and the number of pool guests

the number of children assigned to a class and the number of desks

the number of children assigned to a class and the number of desks

the price of apples and the number of giraffes in Africa

Solve for x: 3x - 5 + 2x = 25 - 5x
VashaNatasha [74]

Answer:

x=3

Step-by-step explanation:

Add 2x and 3x

5x-5=25-5x

move -5x to the other side by adding 5x on both sides:

10x-5=25

Add 5 on both sides:

10x=30

Divide 10 on both sides:

x=3

Hope this helps!
