Graph the inequality y>2/3x-1

Mathematics
1 answer:
xenn [34]3 years ago
5 0

Answer:

graph{y>2/3x-1 [-10, 10, -5, 5]}

Explanation:

First, graph a line with the equation y=23x−1. This equation is in the form y=mx+b. 23 is the slope and −1 is the y-intercept.

graph{2/3x-1 [-10, 10, -5, 5]}

However, we are graphing an inequality so we're gonna have to shade either the area above the line or below the line. First, let's look at the inequality symbols.

> Greater than

< Less than

≥ Greater than or equal to

≤ Less than or equal to

If the inequality includes equal to, then the line will be solid. If not, then the line will be dotted. Since the inequality y>23x−1 doesn't contain the equal to, the line will be dotted.

The direction of the inequality sign matters too. If it's greater than, then the top area will be shaded. If it's less than, then the bottom area will be shaded. Since the inequality y>23x−1 has greater than, the top area will be shaded.

graph{y>2/3x-1 [-10, 10, -5, 5]}

Use the point-slope formula to write an equation of the line that passes through (-5, -4) and (3, -1).
aalyn [17]

Answer:

point slope form: y + 4 = 3/8 (x + 5)       slope intercept: y = 3/8x - 17/8

Step-by-step explanation:

y2 - y1 / x2 - x1

-1 - (-4) / 3 - (-5)

slope = 3/8

y + 4 = 3/8 (x + 5)

y = 3/8x + b

-1 = 3/8(3) + b

-1 = 9/8 + b

-17/8

y = 3/8x - 17/8

Which of the following is a linear function?
disa [49]

Answer:

  • x = y − 4
  • y = 1/5x

Step-by-step explanation:

As written, they all are linear functions.

If we assume that x3 is supposed to be interpreted as x³ = x^3, and that x2 is supposed to be x² = x^2, then the equations containing those terms are not linear equations.

The equation y = 1/5x is usually interpreted to mean y = (1/5)x. If it is intended to be y = 1/(5x), then it is not a linear function either.

___

A linear function is a sum of terms that are either constant or containing a single variable to the first power.
