Question

Find the value of a, if the line 3y =ax+7 will pass through (i) (1,2) ii.( ( 2, -3 )

Answer 1

for passing through point(1,2)
satisfying given equation
3*2=a+7
hence a=-1.


for point(2, -3 )

3*-3=2a+7

or a=-16/2=-8

Answer 2

Answer:

$a = 8$

$(2,-3)</p><p>x=2 y= -3</p><p>3y=ax+7</p><p> 3(-3)=a(2)+7</p><p>= -9=2a+7</p><p>= 2a=7+9</p><p>= 2a=16</p><p>a=$

$16 \div 2 \\ a = 8$
