<h3>
Answer: A and C</h3>
Both matrices are 1 x 4 matrices. This notation says there is 1 row and 4 columns. The number of rows must match up, as well as the number of columns, in order for matrix addition to be possible. This is so the corresponding elements pair up and add together. For instance, the 5 and -2 pair up and add together for matrices A and C.

Answer:
The equation of the line is y = 3/4x - 1/4
Step-by-step explanation:
To find the equation of this line, start by using the two points with the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (2 - 1/2)/(3 - 1)
m = (3/2)/2
m = 3/4
Now that we have the slope, we can use that and either point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = 3/4(x - 3)
y - 2 = 3/4x - 9/4
y = 3/4x - 1/4
