A line passes through the point (10,-1) and has a slope of -1/2
dezoksy [38]

Hi there!

I'm guessing you want to know what the equation of the slope-intercept line is.

The general equation for the slope-intercept line looks like this:

y = mx + b

Where "m" is the slope and "b" is the y-intercept.

Since we know what the slope is and we have the coordinates of a point, you can replace the slope and the value of the coordinates "x" & "y" in the equation and solve for "b" in order to find the whole equation :

y = mx + b

-1 = -1/2(10) + b

subtract "b" from each side of the equation

-1 - b = -1/2(10)

Add 1 to each side of the equation

-b = -1/2(10) + 1

-b = -5 + 1

-b = -4

Divide each side of the equation by -1

b = 4


Since you now know the value of "b" you can go ahead and write the slope-intercept equation with the slope in it and the y-intercept value also (b) :

y = -1/2 + 4


There you go! I really hope this helped, if there's anything just let me know! :)

Learning task 2
evablogger [386]

Step-by-step explanation:

Row 1

  • k=2 ,  Equation: y=2xz

Row 2

  • x=10, k=2

Row 3

  • y= 192,  Equation: y= 4xz

Row 4

  • z= 2, k= 3

Row 5

  • x= 16/3, k= 3/4

<u>Note</u>. <em>The equation should be y = 3/4xz, not y = 3/4xy</em>

In a beaded necklace 3/12, of the beads
Alexxandr [17]

Answer: 7/12 of the beads are blue and green

Step-by-step explanation: To make both denominators of fraction 3/12 and 1/3 equal, you have to change both denominators to the lowest common denominator. Since the LCD (lowest common denominator) is 12 you have to multiply 1/3 by 4 to make the two denominators match.

1/3 x 4/4= 4/12

Then to find the total fraction of both green and blue beads on the necklace, you simply have to add the two fractions together.

4/12+3/12= 7/12

hope this helps :)
