Answer:

f(2) = - 1 and f(4) = 3

Step-by-step explanation:

To evaluate f(2), substitute x = 2 into f(x), that is

f(2) = 2(2) - 5 = 4 - 5 = - 1

To evaluate f(4), substitute x = 4 into f(x)

f(4) = - 3(4) + 15 = - 12 + 15 = 3

Molodets [167]

Answer:

Given points ( -1 ,3 ) and slope(m) = -3

Step-by-step explanation:

<em>The </em><em>equation </em><em>of </em><em>a </em><em>line </em><em>is </em><em>given </em><em>by </em>

<em>y </em><em>-</em><em> </em><em>y1 </em><em>=</em><em> </em><em>m </em><em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>x1</em><em> </em><em>)</em>

<em>y </em><em>-</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>-</em><em>3</em><em> </em><em>(</em><em> </em><em>x </em><em>+</em><em>1</em><em> </em><em>)</em>

<em>y </em><em>-</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>-</em><em>3</em><em>x</em><em> </em><em>-</em><em> </em><em>3</em>

<em>3x </em><em>+</em><em> </em><em>y </em><em>-</em><em>3</em><em> </em><em>+</em><em>3</em><em> </em><em>=</em><em>0</em>

<em>3x </em><em>+</em><em> </em><em>y </em><em>=</em><em> </em><em>0</em>

<em>which </em><em>is </em><em>the </em><em>required </em><em>equation </em>
