First we find the equation of the line. Notice that the line goes through the point (0,c). Since c is on the y-axis, c is the y-intercept. To find the slope take any two points and count the boxes (up or down) from one to the other. Divide that by the number of boxes (left and right) from one to the other. I chose (0,c) and (1,-1) so I traveled down 2 and right 1. Down (negative) 2 and right (positive) 1 gives me a slope of -2/1 = -2.

The equation of a line is given by y = my +b where m is the slope (here -2) and b is the y-intercept (here c). That makes the equation of the line y=-2x+c.

The shading occurs above the line so we use either greater than (>) or the greater than or equal to sign ( \geq ). The way we decide is whether the line is solid (as it is here) or dashed. Here it is solid so we use greater than or equal to.

That makes the correct answer the 5th choice from the top: y \geq -2x+c

the lengths of the four sides as a quadrilateral (in feet) are consecutive integers if the perimeter is 86 ft find the value of
tia_tia [17]

Let x be the shortest side

Let x+1 be the second side

Let x+2 be the third side

Let x+3 be the fourth and longest side

perimeter = s_{1} + s_{2} + s_{3}  + s_{4} \\ 86 = x + (x + 1) + (x + 2) + (x + 3) \\ 86 = x + x + 1 + x + 2 + x + 3 \\ 86 = 4x + 6 \\ 4x = 80 \\ x = 20

Shortest side is 20 cm

Longest side is x+3 so 20+3=23
