Answer:

undefined slope

Step-by-step explanation:

The points contain the same x-value. This means that the line is vertical.

All vertical lines have an undefined slope.

Hope this helps.

Two cars start at the same time, but travel in opposite directions. One car's average speed is 80 miles per hour (mph). At the e

Alinara [238K]

Answer:

50 mph

Step-by-step explanation:

80 mph x 4 = 320 miles. so the first car went 320 miles

520 miles apart- 320 = 200 I subtracted the 320 miles so i can figure out how far the other car went.

200 / 4 hours = 50 mph

Find the equation of the line perpendicular to y=-2/3x -7 that runs through the points (6,1) in slope intercept form

SVEN [57.7K]

The equation of line is:

$y = \frac{3}{2}x-8$

Further explanation:

Given equation of line

$y=-\frac{2}{3}x-7$

Comparing it with the standard form

y = mx + b gives us:

slope = m1 = -2/3

Let m2 be the slope of second line

The product of slopes of two perpendicular lines is -1.

$m_1* m_2 = -1\\-\frac{2}{3} *m_2 = -1\\m_2 = -1 * -\frac{3}{2}\\m_2 = \frac{3}{2}\\Putting\ in\ standard\ form\\y = \frac{3}{2}x +b$

We have to find the value of b. So, Putting the point(6,1)

$1 = \frac{3}{2}(6) +b\\1 = (3 * 3) + b\\1=9+b\\1-9 =b\\b = -8\\The\ final\ equation\ is:\\y= \frac{3}{2}x -8$
