Don't hate me if I'm wrong but I think the first one is 76 but I couldn't find out the second line.
(3x - 2y) / (z + 4)........x = 1, y = -2, z = 3
now we start subbing
((3(1) - 2(-2)) / (3 + 4).....simplify
(3 + 4) / (3 + 4) =
7/7 =
1 <== ur answer
Answer: y=1/2x-4
Explanation:
slope: rise 1 and over 2
y-intercept: -4 or (0,-4)
Answer:
y = -
x + 9
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 = 2x - 3 ← is in slope- intercept form
with slope m = 2
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 (8, 5) into the partial equation
5 = - 4 + c ⇒ c = 5 + 4 = 9
y = -
x + 9 ← equation of line
Answer:
Y= -5x+2
Step-by-step explanation:
y= mx+b where M represent the slope aka X intercept. B represent the initial value aka Y intercept. Hope it help!
