I W㏑ILL MARK YOU BRAINLYEST if you answer all of my problems !!!!!!!!!!!

Give the linear equations, y=7 and x=3

4# identify the vertical line -----------

5# identify the horizontal line -----------

Find the slope of the line passing through the following points. m= y2 - y1
----------
x2 - x1

10# (-4, 8) and (-1, -7)
M=--------

11# (2, 5) and (2,-3)
M=----------

12# (-4, -9) and (0, -9)
M=---------

Find the X & Y - intercepts in each equation.

15# 8x-2y=4 x - intercept---------- y - intercept------------

16# y= -4x+8 x - intercept---------- y - intercept------------

Respuesta :

4# Vertical line is x = 3


5# Horizontal line is y = 7


10# Slope of the line = (-7-8)/(-1-(-4))

= -15/3 = -5


11# Slope of the line = (-3 -5)/(2-2) = -8/0 = infinite, ie the line is parallel to y axis


12# Slope of the line = (-9-(-9))/ ( 0 - (-4)) = 0/4 = 0, ie the line is parallel to x axis


15# 8x - 2y = 4

or, x/0.5 - y/0.5 = 1

or, x/0.5 + y/(-0.5) = 1

Therefore x intercept is 0.5 or 1/2 and y intercept is -0.5 or -1/2


16# y = - 4x + 8

or, 4x + y = 8

or, x/0.5 + y/8 = 1

Therefore x intercept is 0.5 or 1/2 and y intercept is 8


Hope it helps.


Thanks you..!!
