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

Mathematics

son4ous [18]3 years ago

Answer:

The graph of the line y=\frac{2}{3}x+3 that contains the point (-3,1) with a slope of 2/3 is attached below.

Step-by-step explanation:

We know that the slop-intercept form of the equation is

y=mx+b

where m is the slope, and b is the y-intercept.

Given the slope = m = 2/3, and point (-3, 1)

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

-\frac{2}{3}\cdot \:3+b=1

-2+b=1

b=3

so the equation of line will be:

y=mx+b

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

Also, the graph of the line y=\frac{2}{3}x+3 that contains the point (-3,1) with a slope of 2/3 is attached below.

Find the equation of the straight line which passes through the point (-1,3) and make intercept on x - axis as thrice that on y
Triss [41]

Answer:

y = -\frac{1}{3}x + \frac{8}{3}

Step-by-step explanation:

Given

(x_1,y_1) = (-1,3)

Intercept\ on\ x-axis = Intercept\ on\ y-axis.

Required

Determine the equation

First, we calculate the intercepts using:

\frac{x}{a} + \frac{y}{b} = 1

Where

b = Intercept on y axis.

a = Intercept on x axis.

From the question:

a = 3b

The equation becomes:

\frac{x}{3b} + \frac{y}{b} = 1

Multiply through by 3b

x + 3y  = 3b

We have: (x_1,y_1) = (-1,3)

So:

-1 + 3 * 3 = 3b

8 = 3b

Make b the subject

b = \frac{8}{3}

Substitute b = \frac{8}{3} in x + 3y  = 3b to get the equation

x + 3y = 3 * \frac{8}{3}

x + 3y = 8

Make 3y the subject

3y = -x + 8

Make y the subject

y = -\frac{1}{3}x + \frac{8}{3}

3(x-6)+6=5x-6 useing distributive property
neonofarm [45]

Answer:

x=-3

Step-by-step explanation:

3(x-6)+6=5x-6 - Problem

The Distributive property says a(b+c)=ab+ac. Using this knowledge, lets solve.

1) Distribute 3 to x and -6:

3x-18+6=5x-6

2) Combine alike terms: (-18 and 6)

3x-12=5x-6

3) Subtract 3x from both sides:

-12=2x-6

4) Add 6 to both sides:

2x=-6

5) Divide both sides by 2:

x=-3

1,000 bows x 0.75 meters
= 750 meters

We know that Nicole is making 1,000 bows and that each bow requires 0.75 m of a piece of ribbon.  Therefore, we can multiply the number of bows by the length needed to make each bow in order to determine the total meters of ribbon needed to make all the bows - it's like adding 0.75 meters a thousand times for each bow.  When multiplying, you get a product of 750 meters.
