find equation of AB if A(1,0) and B(1,-1)
X=1
Is Triangle ABC has vertices A(2,1) B(4,8) and C(8,-2). Is it isosceles? How do you know?
no and because none of the sides have the same length?
what is the abscissa of the point found on the line y=-2x+5 having ordinate 4
1/2
What is the slope of the line?
5x+5y=−15
-1
Determine the lengths of the diagonals of the trapezoid with vertices A(–3, 3), B(12, 8), C(7, 6), D(0, 7) to find if it is isosceles.
AC does not equal BD so its not isosceles trapezoid
An equation of the line that passes through the point (0,1) and whose slope is 2 is... (in slope intercept form)
y=2x+1
The coordinates of quadrilateral ABCD are A(-3,-1), B(3,1), C(7,5), and D(1,3). Do the diagonals bisect each other at right angles?
hint: are the midpoints the same?
yes
What are the x-intercept & y-intercept of
2x + y = 2?
y = 0, x-intercept = 1
x = 0, y-intercept = 2
What is the slope of the line that is
y=mx+4 and goes through (-2,0)
m = 2
