Answer:
yes, perpendicular
Step-by-step explanation:
perpendicular lines on a graph has opposite reciprocal slope
y=3x-7
3x+9y=9 ( put the equation in the slope intercept form y=mx+b
9y=-3x+9
y=-3x/9+9
y=-1/3 x +9
the slope of the first question is 3
the slope of the second equation is -1/3 x
yes the two lines are perpendicular
Answer:
The lines are perpendicular.
Perpendicular lines have opposite reciprocal slopes.
Opposite reciprocals have a product of –1.
The given line has a slope of 3, and the second line has a slope of –1/3.
