(-2, 11) &amp; (5,6)<br> What is the slope of the equation between these two points?
ololo11 [35]

Answer:

m =\dfrac{-5}{7}

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

  • Two points (-2,11) and (5,6) .

And we need to find out the slope of the equation between the two points. The slope of the line passing through two points , is given by ,

\implies Slope (m) =\dfrac{ y_2-y_1}{x_2-x_1}

  • Here the two points are (-2,11) and (5,6) .So put on the respective values ,

\implies Slope (m) =\dfrac{ 11 - 6}{-2-5}\\\\\implies Slope = \dfrac{5}{-7} \\\\\implies Slope = \dfrac{-5}{7}

<u>Hence</u><u> the</u><u> </u><u>slope</u><u> of</u><u> the</u><u> line</u><u> is</u><u> </u><u>-</u><u>5</u><u>/</u><u>7</u><u> </u><u>.</u>

How do you do coordinates?​
suter [353]

Answer:

Start at (0, 0), or the origin. Just go to (0, 0), which is the intersection of the x and y axes, right in the center of the coordinate plane. 2. Move over x units to the right or left. Let's say you're working with the set of coordinates (5, -4). Your x coordinate is 5.

Ashley had a summer lemonade stand where she sold small cups of lemonade for $1.25 and large cups for $2.50. if ashley sold a to
Levart [38]
The answer is 98 small and 57 large cups.

s - the number of small cups
l - the number of large cups

<span>Ashley sold a total of 155 cups: s + l = 155
</span><span>Ashley earned</span><span>for $265: 1.25 * s + 2.50 * l = 265

</span>s + l = 155
1.25 * s + 2.50 * l = 265
________
s = 155 - l
1.25 * s + 2.50 * l = 265
________
1.25 * (155 - l) + 2.50 * l = 265
193.75 - 1.25 * l + 2.50 * l = 265
193.75 + 1.25 * l = 265
1.25 * l = 265 - 193.75
1.25 * l = 71.25
l = 71.25 / 1.25
l = 57

______
s = 155 - l
l = 57

s = 155 - 57
s = 98
