Which of the following is equation of a line that passes through (-2,1) and (-4,-3)?​
ladessa [460]

Answer:

<h2>y = 2x + 5</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

=======================================

We have the points (-2, 1) and (-4, -3). Substitute:

m=\dfrac{-3-1}{-4-(-2)}=\dfrac{-4}{-2}=2

y=2x+b

Put the coordinates of the point (-2, 1) to the equation:

1=2(-2)+b

1=-4+b           <em>add 4 to both sides</em>

5=b\to b=5

Finally:

y=2x+5

What is the solution to the inequality <br> X+ (7 + 2x) &lt;-3x
dolphi86 [110]

Answer:

x \:  <  \:- 1   \frac{1}{6}

Step-by-step explanation:

The given inequality is

x+ (7 + 2x) <-3x

Expand parenthesis to get

x+ 7 + 2x <-3x

Group similar terms

x+ 2x +3x<-7

Combine similar terms

6x<-7

Divide both sides by 6

x \:  <  \:  -  \frac{7}{6}

Rewrite as improper fraction

x \:  <  \:- 1   \frac{1}{6}
