Question

if (-1,1)is a solution of the equation y=ax+3,then a=​

Answer 1

Answer:

Step-by-step explanation:

Step-by-step explanation:ax-2y=10

.'. X=1 , Y=1

a1-2*1=10

a-2=10

a=10+2

a=12

Answer 2

Answer:

$y = ax + 3 \\ since \: ( - 1,1) \: is \: its \: solution \\ 1 = a( - 1) + 3 \\ 1 = - a + 3 \\ a = 3 - 1 \\ a = 2$
