Answer:
d
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 6 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - , then
y = - x + c ← is the partial equation
To find c substitute (5, - 7) into the partial equation
- 7 = - 2 + c ⇒ c = - 7 + 2 = - 5
y = - x - 5 ← equation of perpendicular line → d

Answer:
So he can buy 15 + he will have on his card left 0.65$
Step-by-step explanation:
20 / 1.29 = 15 song's
20 - 19.39 = 0.65
So he can buy 15 + he will have on his card left 0.65$
Answer:
none of them
but across the line y=x (just a vertical line)
