Answer:

-0.5x + y + 0.5 > 0

Step-by-step explanation:

Let the equation of the line is,

y - y' = m(x - x')

where (x', y') is a point lying on the line

m = slope of the line

Since two points (1, 0) and (3, 1) lie on the line,

Therefore, slope of the line 'm' = \frac{y_2-y_1}{x_2-x_1}

m = \frac{1-0}{3-1}

m = \frac{1}{2}

Equation of line passing through (1, 0) and slope = \frac{1}{2} will be,

y - 0 = \frac{1}{2}(x-1)

y = 0.5x - 0.5

Since, line given in the graph is a dotted line therefore, its an inequality having sign of (> or <).

In this inequality shaded region is above the dotted line therefore, inequality representing the solutions by the shaded region will be,

y > 0.5x - 0.5

-0.5x + y + 0.5 > 0

Amber and her friend Nathan are
Gnesinka [82]

Answer:

{(12-4) + (15-8)}x  = 65

Step-by-step explanation:

The amount Amber earns per week

12-4

The amount Nathan earns per week

15 -8

The total amount per week they earn together

(12-4) + (15-8)

Multiply by x weeks

{(12-4) + (15-8)}x

Set this equal to 65 to be the amount they need to equal 65 dollars

{(12-4) + (15-8)}x  = 65
