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
If you want just 1430/75 in fraction form then:
after you divide it by 5.
If you want the divided number in fraction form then:
both give the same answer so it doesn't matter.
