Answer:
[tex]y=10[/tex]
Step-by-step explanation:
we know that
The y-intercept is the value of y when the value of x is equal to zero
we have
[tex]-7x+3y=30[/tex]
so
For x=0
substitute the value of x in the linear equation and solve for y
[tex]-7(0)+3y=30[/tex]
[tex]3y=30[/tex]
Divide by 3 both sides
[tex]y=10[/tex]
