What is 3 4 and 5 -2 in slope intercept form

ladessa [460]

Answer:

y = - 3x + 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 )

calculate m using the slope formula

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

with (x₁, y₁ ) = (3, 4 ) and (x₂, y₂ ) = (5, - 2 )

m = $\frac{-2-4}{5-3}$ = $\frac{-6}{2}$ = - 3 , then

y = - 3x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (3, 4 )

4 = - 9 + c ⇒ c = 4 + 9 = 13

y = - 3x + 13 ← equation of line

What’s the answer to this?

Softa [21]

Answer:

f(0) = 4

Step-by-step explanation:

f(0) implies that we should find the corresponding f(x) value of when x = 0.

From the table given, when x = 0, f(x) = 4. This is (0, 4).

Thus:

f(0) = 4
