Question

To draw graph of 4x +5y = 19, find y when x = 1

Answer 1

at x=1

y= (19-4)/5=3

now to get graph change the equation to intercept form.

so a= 19/4 and b=19/5

so cut x at 19/4 and y at 19/6

Answer 2

Answer:

Explanation: 4x+5y=19

Put x=1 in Equation

4x1+5y=19

4+5y=19

5y=19-4

5y=15

Y=15/5

Y=3

So, The given equation of the following variables are (x,y)=(1,3)
