The vertices of a triangle are j(1,1) k(2,4) l(5,3) . find the slopes of the lines connecting the vertices. then determine whether the triangle is a right triangle.

The triangle is not a right triangle.

Step-by-step explanation:

The given triangle has vertices

The formula for finding the slope is

The slope of JK is

The slope of JL is

The slope of KL is

The products of the slopes of the adjacent sides are

None of the products is , which means that no adjacent sides are perpendicular. Hence the triangle is not a right triangle.

Yes, the triangle is a right triangle.

Step-by-step explanation:

Since we know that slope formula of the line connecting two points is: , where,

m = Slope of the line.

= Difference between y-coordinates of two points.

= Difference between corresponding x-coordinates of same two points.

Let us find slope of the line connecting points J(1,1) and K(2,4).

Let us find slope of the line connecting points K(2,4) and L(5,3).

Let us find slope of the line connecting points L(5,3) and J(1,1).

Since we know that perpendicular lines intersect at right angles to one another and the slopes of perpendicular lines are opposite reciprocals of each other.

We can see that slope of line connecting points J and K is 3, while slope of the line connecting points K and L is .

Since is negative reciprocal of 3, therefore, the triangle is a right triangle.

i dont know

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
