Answer:

Step-by-step explanation:

Okay, so first of all, when a slope is negative, the line goes down from left to right, not up from left to right. Then, plot the Y intercept as -2. Finally, either go up 2 and left 3 or down 2 and right 3.

Answer:

Graph attached.

Step-by-step explanation:

As we have been given the slope and the y-intercept, we can create a <u>linear equation</u> using the slope-intercept form.

<u />

<u>Slope-intercept form of a linear equation</u>:

y=mx+b

where:

  • m is the slope
  • b is the y-intercept

Substitute the given values into the formula to create an equation for the line:

\implies y=-\dfrac{2}{3}x-2

Now we have an equation for the line, find at least two points on the line by inputting values of x into the found equation:

x=0 \implies y=-\dfrac{2}{3}(0)-2=-2 \implies (0,-2)

x=3 \implies y=-\dfrac{2}{3}(3)-2=-4 \implies (3,-4)

x=-6 \implies y=-\dfrac{2}{3}(-6)-2=2 \implies (-6,2)

Plot the found points and draw a straight line through them (see attachment).

Find the midpoint of the two points
inna [77]
<h3>Answer: D.  (2, 21)</h3>

Explanation:

Imagine that your teacher wanted you to find the midpoint of -3 and 7 on the number line. To do this, you would add up the given values and divide by 2.

(-3+7)/2 = 4/2 = 2

The value 2 is right in the middle of -3 and 7 on the number line. This result is also the x coordinate of the midpoint since the values I used were the x coordinates of the original points.

The y coordinates are handled the same way:

(18+24)/2 = 42/2 = 21

The y coordinate of the midpoint is y = 21

Overall, the midpoint is (2, 21)

It costs a total of R138.90 to purchase 10 loaves of bread and 12 litres of cooidrinks in a store. If the store raises the price
AlladinOne [14]

9514 1404 393

Answer:

  R32.15

Step-by-step explanation:

Let x and y represent the original price of a loaf of bread and a liter of drink, respectively. The two relations given by the problem statement are ...

  10x +12y = 138.90

  10(1.2x) +12(1.1y) = 159.54

Multiplying the first equation by 1.2 and subtracting the second gives ...

  1.2(10x +12y) -(10(1.2x) +12(1.1y)) = 1.2(138.90) -(159.54)

  1.2y = 7.14 . . . . collect terms

  y = 5.95 . . . . . divide by 1.2

The value of x can be found from the first equation.

  10x + 12(5.95) = 138.90

  10x = 67.50 . . . . . . . . . . . subtract 71.40

  x = 6.75 . . . . divide by 10

Then the value of 3x+2y is ...

  3(6.75) +2(5.95) = 32.15

The original price of 3 loaves and 2 liters is R31.15.
