The Slope-Intercept form of the equation of the line is:

Where "m" is the slope of the line and "b" is the y-intercept.
The slope can be found with:

Choose two points from the table. These could be the points (1,-4) and (4,-19). You can set up that:

Substituting values, you get that the slope of this line is:

You can substitute the slope and the first point into the equation in Slope-Intercept form:

Solve for "b":

Therefore, the Equation of this line in Slope-Intercept form is:
The answer is 119 8/14 which simplifys to 119 4/7.
Part a:-
The base of each triangle is 4 inches long.
Their height is 3/2 * 4 = 6 inches.
b
The combined area of the triangular faces = 4 * 1/2 * 4 * 6 = 48 sq ins
c
Surface area of the pyramid = 48 + area of base = 48 + 16 = 64 sq ins.
The answer is 242 cm squared.
