The slope intercept form of this would be y=*3x-1. The formula for slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. I this problem, the y-intercept is -1, so you would plug in -1 for b, so the equation is y=mx-1. The slope is -3, so you plug that in for m, so the equation now becomes y=-3x-1. Hope that helps!!

Y - y1 = -3(x -x1)
y - (-1) = -3(x-4)
y +1 = -3x + 12
y = -3x + 11

Prove the following theorem indirectly. We will give you a start.. . Prove that a triangle cannot have two right angles.. A tria

ladessa [460]

Suppose a triangle had two right angles.
The sum of all angles of any triangle is 180°.
The measure of a right angle is 90°.
By difference, the measure of the other angle can be determined.
Since the two angles have a measure of 90° each, then by difference, the measure of the third angle is 180° - (90° + 90°) = 0°.
If the angle is 0°, there would only be two sides.
A triangle has three sides.
Therefore, a triangle can't have two right angles.
