(1,11/4)(2,25/4)
slope = (25/4 - 11/4) / (2 - 1) = (14/4) / 1 = 14/4 = 7/2
y = mx + b
slope(m) = 7/2
(1,11/4)...x = 1 and y = 11/4
now we sub and find b, the y int
11/4 = 7/2(1) + b
11/4 = 7/2 + b
11/4 - 7/2 = b
11/4 - 14/4 = b
-3/4 = b
so ur equation is : y = 7/2x - 3/4
12.25m^2 because you’re finding area
A=l•W
A=3.5•3.5
A=12.25
C. 1 solution hope it helps
