Writing Equations of Lines
Write the slope-intercept form of the equation of the line given the slope and y-intercept.
Slope = -5, y-intercept = -3
Write the slope-intercept form of the equation of the line given the slope and y-intercept.
Slope = -1, y-intercept = 5
Write the slope-intercept form of the equation of the line.
y – 5 = -10(x – 4)
Write the slope-intercept form of the equation of the line.
Write the slope-intercept form of the equation of the line through the given point with the given slope.
Through: (4,-4), slope = 2
Write the slope-intercept form of the equation of the line through the given point with the given slope.
Through: (-5,1), slope = undefined
Write the slope-intercept form of the equation of the line through the given points.
Through: (3,-3) and (4,0)
Write the slope-intercept form of the equation of the line through the given points.
Through: (3,5) and (0,1)
Write the standard form of the equation of the line given the slope and y-intercept.
Slope = -2, y-intercept = -2
Write the standard form of the equation of the line given the slope and y-intercept.
Through: (1,2), slope = 6
Slope intercept form of a equation is y=mx+c
Where m=slope of the line and c is a Y-intercept
Slope-intercept form of a line where slope=-5 and y-intercept =-3 is
Y=-5x-3
Slope-intercept form of a line where slope=-1 and Y-intercept =5 is
Y=-x+5
Slope-intercept form of a line, y-5=-10(x-4)
y-5=-10x+40
Y=-10x+45 (slope intercept form)
The slope -intercept form of a line passing through (4,-4) and slope =2
Y=2x+c
Substituting( 4,-4) in above we get c=-12
Therefore the equation is y=2x-12
We know that, the vertical line slope is undefined
The equation of line passing through (-5,1) is x=-5
The equation of a line passing through (3,-3), and (4,0)
Slope m=-3/-7=3/7
Now y=3/7x+c
Substitute (4,0) in above equation
C=7/3*4=7/12
Y=3/7x+7/12
The slope intercept form of a equation (3,5) and (0,1)
Then m=4/3
Y=(4/3)x+c
Substitute (0,1) in above equation c=3/4
Then y=(4/3)x+(3/4)
The standard form of a straight line is ax+by=c
Where a, b, c are real numbers
Y=-2x-2
2x+y=-2
The standard form of the equation of a line passing through (1,2) and slope=6
Y=6x+c
Substitute (1,2) in above equation
Then c=-4
Y=6x-4
-6x+y=-4 (which is a standard form)
