y answer is right

Answer 2

Given :

Slope of line ( m ) = 3.4

Intercept made on axis ( c ) = 12

To find :

Value of y when x is 7.

Explanation :

The general equation of a straight line that cuts the y axis at an intercept "c" having slope "m" is $y = mx + c$

Solution :

Substituting the given values in the equation of a general line , we get

                           $y = (3.4) (7) + 12$

      Therefore ,   $y = 35.8$

Final Answer :

Hence , the value of y when x= 7 is 35.8
