Step-by-step explanation:
Here slope of the line (m) = 9
And the line passes through the point (2,10)
Equation is the line is given by
<h2>
y - 10 = 9 (x - 2)</h2><h2>
y -10 = 9x - 18</h2><h2>
y -9x = -18+10</h2><h2>
9x-y +8 = 0</h2>
<em>is </em><em>the </em><em>required </em><em>equation </em><em>of </em><em>the </em><em>line. </em><em> </em>

Answer: She had 200 cards to start with
Step-by-step explanation:
Let x = the amount of cards she had initially. This means she had x cards to start with.
She gave half of the cards she had to a friend. This means she gave her friend x/2 cards. She is left with with (x-x/2) = x/2 cards.
She also gave 1/4 of the remaining cards to her brother. This means that she gave (1/4 × x/2) = x/8 cards to her brother.
Remaining number of cards will be x/2 - x/8 = (4x-x)/8 = 3x/8
She still has 75 cards left. This means
3x/8 = 75
Cross multiplying with 8, it becomes
3x = 75×8 = 600
x = 600/3 = 200
She had 200 cards to start with.
It’s 3/10 if it’s not then do 28
