Given f(x) = -x + 2, find f(-1)
jarptica [38.1K]

f(x) = -x + 2

f(-1)   This means that they want you to find the value of f(x) or y when x = -1.

f(x) = -x + 2     Substitute/plug in -1 into "x" since x = -1

f(-1) = -(-1) + 2     (two negative signs cancel each other out and become positive)

f(-1) = 1 + 2

f(-1) = 3

A line passes through (3, -2) and (6, 2). a. Write an equation for the line in point-slope form. b. Rewrite the equation in stan
koban [17]

Answer:

(a)

Given: A line passes through the points (3, -2) and (6, 2)

Point slope form: An equation of line passing through two points (x_1, y_1) and (x_2, y_2) is given by:

y -y_1=m(x-x_1`)  .....[1] where m is the slope of the line.

Calculate first the slope of the line:

Slope(m) = \frac{y_2-y_1}{x_2-x_1}

Substitute the given points;

m = \frac{2-(-2)}{6-3}=\frac{2+2}{3} =\frac{4}{3}

Substitute the value of m in [1] ;

y - (-2) = \frac{4}{3}(x-3)

y+2=\frac{4}{3}(x-3)     ......[1]

therefore, the equation of line in point slope form is, y+2=\frac{4}{3}(x-3)    

(b)

to find the standard form of the equation [1]

Multiply both sides by 3  in [1] we get;

3(y+2) = 4(x-3)

using distributive property;   a\cdot (b+c) = a\cdot b + a\cdot c

3y + 6 = 4x -12

Subtract 3y to both sides we get;  

3y + 6 -3y = 4x - 12 - 3y

Simplify:

6 = 4x - 3y -12

Subtract 6 from both sides we get;

0 = 4x - 3y -12-6

Simplify:

4x - 3y - 18 =0

Therefore, the standard form of the equation is; 4x - 3y - 18 =0
