What is the slope of the line parallel to y = 3x + 7?
the slope of the line parallel is the same
m= 3
Find the slope of the line 2x + 5y = 10
solve for y
subtract 2x from each side
5y = -2x +10
divide by 5
y =-2/5 x+2
slope is -2/5
Find the vertex of the following absolute value equation.
y = -1/2|5x+2|-3
the x coordinate of the vertex is
5x+2 =0
5x=-2
x= -2/5
the y coordinate of the vertex is -3
(-2/5, -3)
