Graph the line with the equation y - 1/4x +5.​
postnew [5]

Answer:

Y-intercept=5 Slope=-1/4

Step-by-step explanation:

Plot a point on (0,5)

From that point, you can either go down 1 point and right 4 points, or you can go up 1 point and go left 4 points.

Whichever one you choose, plot a point after each 2 movements

if this is too confusing, another point would be (4, 4) then make a line through both points.

HELP ASAP!!! what similarities and differences did you notice between the three types of compound inequalities?
rodikova [14]


Similarities


Adding or subtracting a number from both sides.

Multiplying or dividing both sides by a positive number.

Applying an increasing function to both sides.

Simplifying one or both sides.

Differences


Multiplying or dividing both sides by a negative number changes the direction of an inequality. So we cannot multiply or divide both sides by a variable unless we know that the variable is either always positive or always negative. This is not a concern when solving equalities.

When applying a decreasing function to both sides of an inequality, the direction of the inequality changes.

Swapping both sides of an inequality also changes the direction of an inequality. Again we don't have to worry about this with equalities.
