Answer:

Option 1 is correct.

Step-by-step explanation:

Given If the cos 90° = 0, then the value of sin 0° is

As cos Ф=sin(90-Ф)

because angles are complementary i.e Ф+(90-Ф)=90

∴ cos 90° = sin(90-90)°=sin 0°

cos 90°=0 gives sin 0°=0 as cos 90°=sin 0°

because the angles are complementary i.e 90°+0°=90°

Hence, option 1 is correct

Determine the slope and y-intercept of the linear equation 2x - y = 4
Paul [167]
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
