0.067 is the answer for this
The point-slope form is
m, the slope, is 1/2.
To find b, we plug in the point (6,-3) to the equation:
First, we multiply 1/2 × 6 = 3. Then we subtract 3 from both sides. We find that b is -6.
Therefore, the point-slope equation is:
This is the second option.
a) The gradient of a line perpendicular to AB is -2.
b) equation of line is y=-2x+6
<h3>What is gradient?</h3>
The gradient is the measure of the steepness of a straight line.
a)The gradient of line is
=(-2-2)/(7+1)
=-4/8
=-1/2
So, gradient of a line perpendicular to AB is -2
b)The coordinates of mid point (3, 0)
m = -2
So,
0= -6+ b
b= 6
So, equation of line is y=-2x+6
