Which graph best represents y = 4x + 1?

The graph of y = 4x + 1 is a linear graph with a slope of 4, and a y-intercept of 1

The function is given as:

A linear equation is represented as:

Where:

So, by comparison:

This means that,

The slope of the graph is 4, and the y-intercept is 1

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
