Answer:

A) -1

B) y = -x + 5

Explanation:

Part A

Define the two points:


\textsf{let}\:(x_1,y_1)=(3,2)


\textsf{let}\:(x_2,y_2)=(4,1)

Substitute the defined points into the slope formula and solve for m:


\implies \textsf{slope}\:(m)=(y_2-y_1)/(x_2-x_1)=(1-2)/(4-3)=-1

Part B

Substitute the found slope and one of the points into the point-slope form of linear equation:


\implies y-y_1=m(x-x_1)


\implies y-2=-1(x-3)

Rearrange so that it is in slope-intercept form:


\implies y-2=-x+3


\implies y=-x+5
