Hi there!

Please see the explanation below.  

»»————-　★　————-««  

Explanation:

Recall the meanings of the variables in the slope-intercept equation.

⸻⸻⸻⸻

\boxed{\text{\underline{Slope Intercept Form:}}}\n\ny=mx+b\n---------------\n\boxed{\text{Key:}}\n\n\rightarrow \text{m - slope}\n\rightarrow \text{b - y - intercept}

⸻⸻⸻⸻

  • We already have one point given, the y-intercept. The y-intercept of a line when given a slope intercept form equation is:  (0, b)
  • Using the example, we would graph the point (0,5) as our first point.

⸻⸻⸻⸻

  • To graph the second point, we need to understand the meaning of slope. The slope of a line can be remembered as 'rise over run'.
  • The slope for the given equation is -3.
  • This means we would have to go three units down and then one unit right from the y-intercept. Our new point would be (1,2).

⸻⸻⸻⸻

  • The result should be the graph attached.

What is the value of 7/8 +3/4

Answers

Find the common denominator:

7/8+6/8
= 13/8 or 1 (5)/(8)
Since 3/4 equals 6/8, you do 7/8 + 6/8 = 11/8 and that can be simplified to 1 and 3/8 and put into decimal form like 1.375.

Step-by-step explanation:

Solve the system if equations by substitution

Y=3x-13
3x+2y=19

Answers

\left \{ {{y=3x-13} \atop {3x+2y=19}} \right. \n\nSubstitution\n\n3x+2(3x-13)=19\n\n3x+6x-26=19\n\n9x-26=19\ \ \ |add\ 26\n\n9x=45\ \ \ | divide\ by\ 9\n\nx=5\ny=3x-13=3*5-13=15-13=2\n\n\nx=5\ny=2

The solution to the system of equations is x = 5 and y = 2.

Given that:

The system of equations:

y = 3x - 13                                   (1)

3x + 2y = 19                                 (2)

Step 1: Solve equation (1) for Y:

y = 3x - 13

Step 2: Substitute y from equation (1) into equation (2):

3x + 2(3x - 13) = 19

Step 3: Simplify the equation and solve for x:

3x + 6x - 26 = 19

9x - 26 = 19

9x = 19 + 26

9x = 45

x = 45/9

x = 5

Step 4: Substitute x = 5 into equation (1) to find Y:

y = 3(5) - 13

y = 15 - 13

y = 2

So, the values of x and y are 5 and 2, respectively.
