Question

The graph of the equation -5x+By=18 is a like that passes through (-6,-2). What is the Value of B?

Answer 1

Substitute the x and y values

$-5(-6)+B(-2)=18$

Simplify

$30+(-2)B=18$

Subtract 30 from both sides

$(-2)B=18-30$

Simplify 

$(-2)B=-12$

Divide both side by (-2)

$B= -\frac{12}{2}$

Simplify

$B=6$
