Answer:
y = - 2x + 13
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 )
Here m = - 2 , then
y = - 2x + c ← is the partial equation
To find c substitute (4, 5) into the partial equation
5 = - 8 + c ⇒ c = 5 + 8 = 13
y = - 2x + 13 ← equation of line
The green line is LM
The red line is JM
The blue point is at the coordinates (2/3, -14/3)
you'll have to excuse the way my graph looks. my graphing application on my computer is weird
4 x + 10 = - 26
subtract 10 from both sides:
4 x + 10 - 10 = - 26 - 10
refine:
4 x = - 36
Divide both sides by 4 :
4 x / 4 = - 36 / 4
refine : - 36 / 4
x = - 9
hope this helps!
