Y-y1= m(x-x1) point-slope form
y-0= -3(x-5)
solve this point-slope form to slope-intercept form. Use the information to graph the line.
well, the table has 5 points in it, let's pick any two hmmm say let's use hmmm (2 , 7) and (6 , 17)

when x = 0, from the table, y = 2, so there's the y-intercept.
It would be "twelve thousandths"
12
since the difference of the first and third value is ten, each value is five more than the previous value
135.78 rounded to the nearest tenth is 135.8.
