Y = - 4x + 3 & x - 4y = 8 : parallel or perpendicular or neither

perpendicular

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4x + 3 ← is in slope- intercept form

with slope m = - 4

x - 4y =  8 ( subtract x from both sides )

- 4y = - x + 8 ( divide through by - 4 )

y = x + 2 ← in slope- intercept form

with slope m =

Since the slopes are not equal the lines are not parallel

- 4 × = - 1

Then the lines are perpendicular

6 and 24

step-by-step explanation:

6 x 4 = 24

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
