Answer:

The length of side AB is \sqrt{50} units.

The length of side BC is \sqrt{65} units.

The length of side AC is \sqrt{145} units.

Step-by-step explanation:

To find the length of each side, we use the formula for the distance between two points.

Distance between two points:

Points (x_1,y_1) and (x_2,y_2). The distance between them is given by:

D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Side AB:

Points A(-3,6),B(2,1). So the distance between them is:

D = \sqrt{(2-(-3))^2 + (1-6)^2} = \sqrt{50}

The length of side AB is \sqrt{50} units.

Side BC:

Points C(9,5),B(2,1). So the distance between them is:

D = \sqrt{(2-9)^2 + (1-5)^2} = \sqrt{65}

The length of side BC is \sqrt{65} units.

Side AC:

Points A(-3,6),C(9,5). So the distance between them is:

D = \sqrt{(9-(-3))^2 + (5-6)^2} = \sqrt{145}

The length of side AC is \sqrt{145} units.

lilavasa [31]
9x +5y= -45 put in standard form y= mx+b coefficient of x is the slope, b is the y intercpept 5y= -9x -45 y= -9/5 x -45 graphing will start at -45 on the y axis from that point go down 9 to the right 5 for the slope continue and graph minimum 2 points to draw the line hope this helps
