What is the slope of the line that is perpendicular to a line whose equation 3y=-4x+2?
Zarrin [17]
The slopes of lines perpendicular to each other are opposite reciprocals. So, if you are given that the slope of a line is 3 and need to find the slope of a line perpendicular to that line, you'd flip that number around and negate it, leaving you with -1/3.

To find the slope of the given line, first get it into slope-intercept form (y - mx + b, where m is the slope and b is the y-intercept).

    3y = -4x + 2
    y = -4/3x + 2/3

The slope is -4/3. To find the slope of a perpendicular line, find its opposite reciprocal. It is 3/4.

Answer:
3/4 (the first option)

A line has a slope of 0.5<br> and passes through the point (0,5). What is the equation of the line?
EleoNora [17]

Step-by-step explanation:

Hi there!

From the question;

The slope of the line is 5/10 or 0.5.

Also the equation of the line passes through the point (0,5).

Note: Use one point formula. {i.e (y-y1)=m(x-x1)}

So, use the formula here and keep the values;

(y-5) = 5/10(x-0)

or, 10(y-5) = 5x

or, 10y-50 = 5x

or, 5x - 10y +50 = 0

Therefore, the required equation is 5x - 10y +50 = 0 or x-2y+10 = 0.

Hope it helps!

Solve |x| + 7 &lt; 4. Please help
PilotLPTM [1.2K]

Answer:

  no solution

Step-by-step explanation:

Subtract 7 from both sides of the inequality:

  |x| +7 -7 < 4 -7

  |x| < -3

This has <u>no solution</u>, because an absolute value cannot be negative.
