Graph y > - 3/4x + 3

Here's what the graph would look like:

You just graph it like a normal line, but make sure the line is dashed because you are looking for all greater values, not greater than or equal to.

Shade the area above the line because it is greater.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
