This is in slope-intercept form, so you can think of it as being y=mx+b. Invert m (the slope) and flip its sign, and then substitute the x and y values in and solve for b. The answer is y=7/2x-20.
Step-by-step explanation:
a. 3 1/7 b. 3 1/6 and c. 2
Step-by-step explanation:
A number that is negative is less than 0, so



So this function is negative, when x is less than -2
