Question

Find A given that (-2, a) lies on y = -3x+ 7

Answer 1

Answer:

a is 13

Step-by-step explanation:

here,

x= -2

y= a,because y = m(x)+ c

so

a = -3(-2) +7

a= 6+7

a=y=13

Answer 2

Answer:

13

Step-by-step explanation:

Since the point (-2,a) lies on line y=-3x+7

The coordinates will satisfy the equation of the line.

Therefore, we have,

=> a = -3(-2)+7

=> a = 6+7

=> a = 13

Hence the required value of a is 13
