Question

Which function is graphed at the right ?

Answer 1

2. G)-11

3. C

4) F. y=1/2x+2

Explanation:

Answer 2

A

Explanation:

Remark

The easiest way to do this is to take the two intercepts (x and y)

x intercept: (-4,0)

y intercept: (0,2 )

Givens

y2 = 2

y1 = 0

x2 = 0

x1 = - 4

Equation

m = (y2 - y1)/(x2 - x1)

Solution

m = (2 - 0)/(0 - - 4)

m = 2/4 = 1/2

Find b

y = mx + b

y = 2

x = 0

2 = 1/2x + b

2 = 1/2*0 + b

b = 2

Answer

y = 1/2 x + 2
