Answer:

Step-by-step explanation:

you need to turn the second y equation into the correct format, so it needs to be y=. Subtract the 1 from the left side and but it on the right side. Your equation should y=3x-1. To graph this on paper, you would go 1 down on the y axis, then rise (go up) 3 and run ( go over) one.on a calculator plug it into the y1 function and y2 function and then press graph.

What is the equation of the line, in slope-intercept form, that passes through (3,-1) and (-1, 5)?

Dimas [21]

Answer:

$2y = -3x+7$

Step-by-step explanation:

The coordinates are (3,-1) and (-1,5)

<u><em>Finding the slope :</em></u>

Slope = $\frac{rise}{run}$

Slope = $\frac{5+1}{-1-3}$

Slope = $\frac{6}{-4}$

Slope = $-\frac{3}{2}$

<u><em>Now Finding y-intercept.</em></u>

For this, we'll take any point

Let it be (3,-1)

So,

Point = (x,y) = (3,-1)

=> x = 3, y = -1

<u><em>Putting in slope intercept form to get b</em></u>

=> $y = mx+b$

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

=> b = -1 + $\frac{9}{2}$

=> b = $\frac{7}{2}$

<u><em>Putting m and b in the slope intercept form to get the required equation of line</em></u>

=> $y = mx+b$

=> $y = \frac{-3x+7}{2}$

=> $2y = -3x+7$

What is the sum of 1/9, 2/3, and 5/18?<br> A. 19/18<br> B.4/15<br> C. 12/9<br> D. 8/20

kari74 [83]

Answer:

19/18

Step-by-step explanation:

The GCF of 9, 3, and 18 is 18.

Each denominator must be multiplied to 18, and as a result what you multiply in the denominator MUST be multiplied in the numerator.

9 * 2 = 18

1 * 2 = 2

2/18

3 * 6 = 18

6 * 2 = 12

12/18

5/18

Add all three fractions together:

12/18 + 5/18 + 2/18 = 19/18
