The perpendicular line will have a slope of b/a.
To find this, we first have to solve our equation for slope intercept form.
ax + by = c ----> subtract ax
by = -ax + c ----> divide by b
y = -a/bx + c/b.
So we know the slope of this equation to be -a/b. Since perpendicular lines have opposite and reciprocal slopes, we know we can simply flip the fraction and make it a negative to get the new slope of b/a.
Answer:
2m+3mn-5
Step-by-step explanation:
2m+n x 3m + (-5)
2m +3mn + (-5)
2m +3mn -5
Answer:
A
Step-by-step explanation:
The x-intercepts are the roots of a parabola. Specifically, when a parabola is in the form
, where h and k are real numbers, the roots are
and
.
Our parabola has a plus, though. That's a problem, right?
No!
, so there's no problem. So, our roots are
and
.
So, the answer is A and we're done!
