Answer:
y = -
x
Step-by-step explanation:
the equation of a linear function in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 8, 2) and (x₂, y₂ ) = (1, - 4) ← 2 ordered pairs from the table
m =
=
=
= - 
the ordered pair (0, 0 ) indicates the line crosses through the origin, then
c = 0
y = -
x + 0 , that is
y = -
x ← equation of linear function
Answer:
x = ± 10
Step-by-step explanation:
to solve the equation let y = 0 , that is
100 - x² = 0 ( add x² to both sides )
100 = x² ( take square root of both sides )
±
= x , that is
x = ± 10
Answer:
30 because 3 x 5=15 then x2 it's 30
3y+14=44
Answer: First step is to subtract 14 from each side
3y = 30 (divide each side by 3)
y = 30/3, y = 10
