Get to y=mx+b form
m=slope
b=yint

2x-y=4
minus 2x from both sides
-y=-2x+4
times -1
y=2x-4
slope=2
yint=-4

equation of horizontal line is y=value

slope=rise/run, so rise is 0 and run is inifnity so 0 is slope

ycoordinate oof every point of a horizontal ine is the value above mentioned (value)


equation of vertical line is x=value

slope is rise/run, since run=0, it is infinity/0 which is undefined, slope=undefined

xcoordinate is equalt to the value (x=value)

general form of the equation of a line is y=mx+b or ax+by=c
every line has an equation that can be writeen in slope-intercept form

the line may not visually appear to have the slope indecated because somethimes the tick marks are not equal distance (use square viewer)




Determine the slope and y-intercept of the linear equation 2x - y = 4
2

The equation of a horizontal line is y=value. The slope of a horizontal line is 0. The y-coordinate of every point on the graph of a horizontal line is value (the one from y=value). The equation of a vertical line is x=value. The slope of a vertical line is undefined. The x-coordinate of every point on the graph or vertical line is value (x=value). The general form of the equation of a line is ax+by=c. Every line has an equation that can be written in slope-intercept form. When a graphing utility is used to sketch a straight line, the graph of the line may not visually appear to have the slope indicated by its equation because  the tick marks are not equally spaced

the cosine of an angle is the ratio of the length of the leg_______that angle to the length of the _________.?help please
krok68 [10]

Answer:

The cosine of an angle is the ratio of the length of the leg adjacent to the angle to the length of the hypotenuse.

Step-by-step explanation:

  • In a right angled triangle, the cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse.
  • Also it is the sine of the complementary angle.
  • The abbreviation is cos
  • The longest side of the triangle is called the hypotenuse,
  • The side opposite the angle theta is called the opposite side,
  • The third side is called the adjacent side.
  • Therefore, cos(\theta) = \frac{adjacent}{ hypotenuse}

A cake has a circumference of 25 1/7 inches. What is the area of the cake? Use 22/7 to approximate pi
Novosadov [1.4K]
To calculate for area given the circumference we proceed as follows:
C=2πr
where:
r=radius
thus given that C=25 1/7 in=176/7
thus plugging in our formula to solve for r we get:
176/7=2πr
thus
r=4.002~4.00 in
hence the area will be:
A=πr²
A=π×(4²)
A=50 2/7 in²
