Write the equation of a line in slope-intercept form that is perpendicular to the line y = 3/5 = 1 and passes through the point

4vir4ik [10]

The slope of the line $y=\frac{3}{5} x-1$ is $m=\frac{3}{5}$ .

The line perpendicular to the above line has slope $-\frac{1}{m} =-\frac{5}{3}$

Its equation is $y=-\frac{5}{3} x+c$ . Since this line passes through, $(-9,4)$ ,

$4=-\frac{5}{3} )(-9)+c\\ c=-11$

Thus the equation of the line in slope intercept form is $y=-\frac{5}{3} x-11$

Distance between (-4,4) and (2,4)

9966 [12]

For this case we have that by definition, the distance between two points is given by:

$d = \sqrt {(x_ {2} -x_ {1}) ^ 2+ (y_ {2} -y_ {1}) ^ 2}$

We have to:

$(x_ {1}, y_ {1}) = (- 4,4)\\(x_ {2}, y_ {2}) = (2,4)$

Substituting:

$d = \sqrt {(2 - (- 4)) ^ 2+ (4-4) ^ 2}\\d = \sqrt {(2 + 4) ^ 2 + (4-4) ^ 2}\\d = \sqrt {(6) ^ 2 + (0) ^ 2}$

$d = \sqrt {36}\\d = 6$

ANswer:

$d = 6$

An angle measures 156° less than the measure of its supplementary angle. What is the measure of each angle?

GrogVix [38]

Answer:

12° and 168°

Step-by-step explanation:

If x is the angle, and y is the supplementary angle, then:

x + y = 180

x = y − 156

Solve the system of equations using substitution:

y − 156 + y = 180

2y = 336

y = 168

Plug back into either equation to find x:

x = 12
