Answer:

f(x) = 3x

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)

m = $\frac{3-0}{1-0}$ = 3 , then

y = 3x ← is the equation of the graphed line

(-4,6); slope = -3/4

Ostrovityanka [42]

Answer:

y = - $\frac{3}{4}$ x + 3

Step-by-step explanation:

Assuming you require the equation of the line

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - $\frac{3}{4}$ , thus

y = - $\frac{3}{4}$ x + c ← is the partial equation

To find c substitute (- 4, 6) into the partial equation

6 = 3 + c ⇒ c = 6 - 3 = 3

y = - $\frac{3}{4}$ x + 3 ← equation of line

Which equation gives the number of 1/3 inches that are in 5/6inch?

Annette [7]

Answer:

$2\frac{1}{2}$

Step-by-step explanation:

Let

x ----> the number of 1/3 in that are in 5/6 in

To find out the number of 1/3 in that are in 5/6 in, divide 5/6 by 1/3

$x=\frac{5}{6}:\frac{1}{3}$

Multiply in cross

$x=\frac{15}{6}$

Convert to mixed number

$\frac{15}{6}=\frac{12}{6}+\frac{3}{6}=2\frac{3}{6}=2\frac{1}{2}$
