The tide level goes down all evening, and Hamid’s instruments read 11 ft above his marker 1 hour before he arrived. Write the equation in slope-intercept form of the line that represents today’s tide level y relative to the marker over time x, if Hamid knows the line is parallel to the graph of yesterday’s data, y=−8x− 2.

y - 11 = -8(x - 1)

Step-by-step explanation:

We are told Hamid’s instruments read 11 ft above his marker 1 hour before.

Where y is tide level and x is time.

Thus, x1 = 1 and y1 = 11

Since graph of yesterday's data is y = -8x - 2,then in slope intercept form, the equation parallel is;

y - y1 = m(x - x1)

m is -8.

Thus; y - 11 = -8(x - 1)

the answer is a.
