What is the equation in slope-intercept form of the line

Natali5045456 [20]

Answer:

y = (-4/3)x + 4

Step-by-step explanation:

Let y = mx + b, be the equation of the line in slope intercept form where we need to find m and b.

Perpendicular to y = (3/4)x - 5, means that m = - (1 / (3/4) ) = - 4/3

So, at this point, y = (-4/3)x + b.

Crossing the x - axis at 3 means that (3, 0) is a point on the line, where we note that x=3 and y=0.

Thus, we plug in these values into the equation y = (-4/3)x + b, to get

0 = (-4/3)(3) + b

0 = -4 + b, so that

b = 4.

Hence, the answer is:

y = (-4/3)x + 4

Find x and y…………….????????

emmasim [6.3K]

Answer:

$let \: \alpha \: be \: the \: 45 \\ \tan( \alpha ) = \frac{p}{b} \\ \tan(45) = \frac{x}{3 \sqrt{2} } \\ 1 = \frac{x}{3 \sqrt{2} } \\ x = 3 \sqrt{2} \\ by \: using \: pythagoras \: therom \\ {y}^{2} = {3 \sqrt{2} }^{2} + {3 \sqrt{2} }^{2} \\ {y}^{2} = 18 + 18 \\ y = \sqrt{36} \\ y = 6$

SIMPLE MATH PROBLEM PLZ ANSWER<br><br> u can pick more than one..

7nadin3 [17]

its the first one 6k - 5

if u were to distribute u need to remember that 6 is negative so it changes -k to a positive 6k and then you would time 4 by -6 which would be -24 but u would just write it like 19 + 6k - 24. then u would add 19 to both sides by 19 which would be like adding 19 to -24 which would equal to -5 so it would equal to 6k - 5.

hope I explained the steps well enough for you.

Two sides of a four-sided figure have negative slopes. Which are the endpoints of the sides of this figure? (–4, –4), (–4, –1),

Inessa05 [86]

Answer:

(1,4) (2,1) (5,1) (4,4)

Step-by-step explanation:

The options are:

(-4,-4) (-4,-1) (-1, -4) (-1,-1)

(-2,-4) (-1, -1) (1,-1) (2, -4)

(1,1) (2,4) (5, 4) ( 4,1)

(1,4) (2,1) (5,1) (4,4)

The only one which has two sides with negative slopes is the last one.

Slope of the side that passes through (1,4) and (2,1): (4 - 1) / (1 - 2) = -3

Slope of the side that passes through (4,4) and (5,1): (4 - 1) / (4 - 5) = -3
