Question

To draw graph of 4x+5y=19, Find y when x=1.
(A) 4
(B) 3
(C) 2
(D) -3

Answer 1

4x + 5y = 19
4(1)+5y=19
5y=19 - 4
5y=15
y=15/5
(B) y=3

Answer 2

Hello dear,

● Answer -
(B) y = 3.

● Step-by-step calculation -
Substituting x = 1 in given equation
4x + 5y = 19
4(1) + 5y = 19
4 + 5y = 19
5y = 19 - 4
5y = 15
y = 15/5
y = 3

Therefore, y = 3 when x = 1. Now you can plot the graph using point (1,3).

Hope this helps you.
Thanks for asking question..
