Question

if (4,19) is a solution of the equation y=ax +3 then a= a)3 b)4 c)5 d)6​

Answer 1

Answer:y=ax +3

19=4a+3

19-3=4a

16/4=a

4=a

option b is the correct answer

Explanation:

Answer 2

Answer:

Here is your answer

Explanation:

Given

y = ax + 3

Solution

According to the linear equation in two variables

0 = ax + 3 - y

If coordinates are (4,19) in the form of (x,y)

Then x = 4 and y = 19

So the value of x is 4

Correct option is b
