Find the equation of the line perpendicular to y= -2x+1 that also intersects the point (8, 2)

Mathematics
1 answer:
Kay [80]3 years ago
4 0

The slope of the perpendicular is the negative reciprocal of the original line, so m = -1/(-2) = 1/2.

The general line of slope m through (a,b) is

y - b = m(x-a)

So the line we seek is

y - 2 = \frac 1 2 ( x - 8)

y = \frac 1 2 x - 2

Answer: y = 1/2  x + -2

Find two supplementary angels such that the measure of the first angle is 38° less than three times the measure of the second
stiks02 [169]


angle 1+ angle 2=180    supplementary angles add up to 180

angle 2=x     assign angle a variable

angle 1= 3x-38      find equation for first angle

3x+x-38=180      set both angles added together equal to 180

4x-38=180        combine like terms

4x=218        add 38 to both sides

x=54.5        divide by 4

angle 2= 54.5

angle 2= (3x54.5)-38   plug back in and solve

angle 1= 125.5
