Question

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

Answer 1

Solutions 

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 (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 isax+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

Answer 2

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)
