What is the equation of the line that passes through the point (8,-3) and has an undefined slope?

BARSIC [14]

Answer:

x = 8

Step-by-step explanation:

A line with "undefined" slope is a vertical line, whose equation is of the form ...

x = constant

In order for the line to go through a point with an x-coordinate of 8, the constant must be 8.

x = 8 . . . . . a vertical line through (8, -3)

Write the equation of a line that is parallel to 3x+2y=10 and passes through the point (4,-5). Answer in slope-intercept form.

SCORPION-xisa [38]

The equation of line is:

$y = \frac{-3}{2}x+1$

Further explanation:

The standard form of equation in point-slope form is:

$y = mx+b$

Given equation is:

3x+2y=10

We have to convert it into point slope form, for which we have to isolate y on one side of equation

$3x+2y = 10\\2y = -3x +10\\y = \frac{-3}{2}x + \frac{10}{2}\\y = \frac{-3}{2}x + 5$

Comparing with standard form:

m = -3/2

As the new line is parallel to given line, their slopes will be equal

So,

$y = \frac{-3}{2}x+b$

To find the value of b, putting the given point (4,-5) in equation

$-5 = \frac{-3}{2}(4)+b\\-5 = -6+b\\b = -5+6 \\b = 1\\So\ the\ equation\ is:\\y = \frac{-3}{2}x+1$

Line AB contains points A (−6, 3) and B (2, −5). Line AB has a slope that is?????

vladimir1956 [14]

The slope is 1

Difference between the first and second y is 8
Difference between the first and second x is also 8

(8,8) simplifies to 1

Hope this helps!

Please crown;)
