Respuesta :
the lines are parallel bc if you change -10x+y=4 into y=10x+4 they will have the same slope of m=10x
solve the second equation for y
-10x+y=4
y=10x+4
so we have the 2lines
y=10x-2
y=10x+4
both are written in slope intercept form do the coefficient of x is there slope. since both slopes are the same, namely 10, the two lines are parallel
-10x+y=4
y=10x+4
so we have the 2lines
y=10x-2
y=10x+4
both are written in slope intercept form do the coefficient of x is there slope. since both slopes are the same, namely 10, the two lines are parallel
