Which table shows the equation y=3x+2.
a: table 1 because when substituting (-1,-1) it makes both sides of the equation equal and so do the other points in the table
b: none, both table 1 and 2 have coordinate points that do no lie on the line of the equation.
c: both table 1 and 2 work for the equation for all points
d: table 2 because when finding the slope between (2,8) and (-4,-10) you get 3. then substituting (2,8) in gives you a y-intercept of 2 and this works for all points.

In a coastal town, the humidity, measured in grams of water per kilogram of air, increases by 43% for every 1 degree celsius increase in temperature. a scientist observes that the humidity on monday morning is 5.75 grams per kilogram. he wants to know how much the temperature must increase for the humidity to reach at least 49.17 grams per kilogram. let t represent the increase in temperature, in degrees celsius, from monday morning's observation. write an inequality to represent the situation, and use it to determine the desired temperature increase.
