Given this equation what is the value of x at the indicated point?

x= [?]

Answer 1

Answer: x = -2

Explanation:

To get the answer, substitute the given y value to the slope formula.

y = 7/2x + 3

-4 = 7/2x + 3

7/2x = -4 - 3

7/2x = -7

7x = -14

x = -2

Answer 2

-4

Explanation:

y = 7/2x +3

or ,-4 = 7/2x+3 (being the co-ordinate x ,-4 lies on the line y = 7/2 x+3)

or, 7/2x =-4-3

or, 7/2x=-7

or, 7x =-14

or, x = -14/7

therefore x=-2
