A matrix is diagonal if
In other words, you want non-zero elements only when the indices of the row and the column are the same: the first element of the first row must be non zero, the second element of the second row must be non-zero, and so on. All other elements must be zero.
Step-by-step explanation:
(x1,y1) = (-1,-1)
(x2,y2) = (2,-2)
m = (y2 - y1)/(x2 - x1)
m = (-2 + 1)/(2 + 1)
m = -1/3
Option → C
The answer is B. common cold
Your answer is c ur welcome
Answer:
D) y = -1/2x + 4
Step-by-step explanation:
Points on the graph: (0, 4) and (8, 0)
Slope:
m=(y2-y1)/(x2-x1)
m=(0 - 4)/(8-0)
m= -4/8
m = -1/2
Slope-intercept:
y - y1 = m(x - x1)
y - 4 = -1/2(x - 0)
y - 4 = -1/2x
y = -1/2x + 4
