Graph the line that contains the point (-3,1) with a slope of 2/3

Mila [183]

Answer:

The graph of the line that contains the point $(-3,1)$ with a slope of 2/3.

Step-by-step explanation:

As the line contains the point (-3, 1) with a slop 2/3

Given the slop-intercept form of the line equation

y = mx+b

Here,

m = slope

b = y-intercept

Substituting the values in the slop-intercept form of the line equation

$y = mx+b$

$1 = \frac{2}{3} (-3) + b$

$1 =- 2 + b$

switching sides

$-2+b=1$

$b=3$

Now Substituting the value of $b=3$ in the slop-intercept form of the line equation

$y = mx+b$

$y=\frac{2}{3} x+3$

Hence, the line of the equation will be: $y=\frac{2}{3} x+3$

Therefore, the graph of the line that contains the point $(-3,1)$ with a slope of 2/3.

<h3>If you combine like terms you get :</h3>

5x = 24

Step-by-step explanation:

$- 7 + 5x - 2 = 15$

Combine like terms

$5x = 15 + 7 + 2$

Further Workings :

Simplify

$5x = 24$

$\frac{5x}{5} = \frac{24}{5} \\ \\ x = 4.8$
