Question

Find if point (4,-3) lies on the line 2y=ax+6

Answer 1

Given 2y=ax+6,,, point (4,-3) lies on this line.,,,, so this point must satisfy the equation of given line,,, ie

2(-3)=a(4)+6

-6=4a+6

-6-6=4a

-12=4a

(-12)/4=a

a=(-3)

ALL THE BEST

Answer 2

Hey

Here is your answer,

The point (4,-3) lies on the line 2y=ax+6, the point 4 lies on x-axis whereas -3 lies on y-axis,

so, x = 4 and y = -3

substitute the values of x and y in the line equation,

2y = ax+6

2(-3) = a(4) + 6

-6 = 4a + 6

moving 6 to left hand side,

- 6 - 6 = 4a

4a = -12

a = -12/4

a = -3
