What is the common difference for data listed in the second column? Altitude (ft) Boiling Point of Water (oF)
1000 210.3
2000 208.4
3000 206.6

1.8

-1.8

-3.6

2.8

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

just sum

10 + 10 = 20

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
