Answer:

A

Step-by-step explanation:

Use a^2 + b^2 = c^2 in each case.

9 + 81 = 91

90 = 91 False

No right triangle

convert the linear equation 3x-2y=5 to point slope form. use the point with an x-coordinate equal to 1
Mademuasel [1]
When x = 1,  y = (5 - 3) / -2  = -1 ,  let x1 = 1 and y1 = -1
2y = 3x - 5
so slope = 3/2

y - y1 = m(x - x1)

y -(-1) = (3/2)(x - 1)

y + 1 = 3/2 ( x - 1)  <-----    answer
