5a - 4a = -9 - 8a
a = -9 - 8a
9a = -9
a = -1
Good day ~_~ /////////////
Its B. 180 trust lol i got you
Answer:
y = - x +
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 )
Rearrange 4y = 5x + 3 into this form by dividing the 3 terms by 4
y = x + ← in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - , thus
y = - x + c ← is the partial equation
To find c substitute (3, - 2) into the partial equation
- 2 = - + c ⇒ c = - 2 + =
y = - x + ← equation of perpendicular line
