Question

Consider the function y=10-4x , if value of x =-1 then the value of 'y' is *

a. 2
b. 14
c. 6
d. -2

Answer 1

After substituting x=-1 into the linear equation y=10-4x, we solve for y, finding that y=14. The correct answer is option b.

Step-by-step explanation:

The question provided requires us to substitute the value of x into the linear equation y=10-4x to find the corresponding value of y. We are given that x = -1, so we substitute that into the equation:

y = 10 - 4(-1)

Now, we solve for y:

y = 10 + 4

y = 14

The correct option is b. 14.
