Find the slope of the line that contains the following points. R(-3, 5), S(3, -2) 7/6 7/6 undefined
Musya8 [376]

Answer:

-\frac{7}{6}

Step-by-step explanation:

We can use the slope formula for the segment that joins any two points (x_1, y_1) and (x_2, y_2):

slope=\frac{y_2-y_1}{x_2-x_1}

which in our case gives:

slope=\frac{y_2-y_1}{x_2-x_1}  = \frac{-2-5}{3-(-3)}=\frac{-7}{6} =-\frac{7}{6}

What is the equation 8x-3y=6-4x in Stanford form?
IgorLugansk [536]

Answer:

12x - 3y = 6

Step-by-step explanation:

Standard form is written this way: Ax+By=C

However, in this case, we just have to simplify 8x-3y=6-4x, as it is already mostly in standard form.

So, to do this, we have to combine like terms.

The only like terms that can be combined are -4x and 8x.

So, we add 4x to both sides, and we get: 12x - 3y = 6.

Does anybody understand writing equations in slope intercept form?
aleksandr82 [10.1K]

slope intercept form

y=mx+b

where m is the slope and b is the y intercept

if we change from point slope form

y-y1 = m(x-x1)

we distribute

y-y1 = mx -x*x1

then add y1 to each side

y = mx -x*x1+y1


remember x and y are variables and should stay in the equation

m,x1,y1 are numbers from the problem

you may have to calculate the slope (m) from the formula

m = (y2-y1)/(x2-x1)  from two points on the line

What is the relationship between the lines with the following equations? 2x+8y=16 y=4x+7
dimulka [17.4K]
They are perpendicular because when you change 2x+8y=16 to slope intercept form it becomes y= -1/4x+2 and the slope (-1/4) is the negative reciprocal of 4, which is the slope for your other equation.

Please comment if you have any questions :)
