4x(-2) + 4 x 7 4x5 + 2x(-1) =[-8 20]
[28 -2 ]
Answer:
y = - 10x - 6
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 slope m = - 10, hence
y = - 10x + c ← is the partial equation
To find c substitute (- 1, 4) into the partial equation
4 = 10 + c ⇒ c = 4 - 10 = - 6
y = - 10x - 6 ← equation of line

Let n be the number 18=60% of n
18=0.6n
18/0.6=n
