Find k so that the line through(k-1,k+2) and (4,-1) is perpendicular to the line through (-3,2) and (2,5).

k = 2

Step-by-step explanation:

Formula to find a slope:

Coordinates of the first line:

Coordinates of the second line:

Slopes of the lines:

Since m₁ = - 1/m₂, we have:

So the answer is 2

first one because it can't have a fraction in it

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
