Answer:

x = 7, y = 2

Step-by-step explanation:

x= 4y -1

since x is by itself 4y-1 will substitute for x in the other equation x+2y=11

it will become 4y-1+2y=11

+1 +1

add one to both sides since is doesn't have a variable.

it will become 4y+2y= 12 now add 4y+2y

becomes 6y=12

6 6

divide by 6 on each side and you get y=2.

now x=4(2)-1 you will substitute y into the first equation.

x=8-1 subtract 8 from 1 to get 7.

x=7

y=2

What is the slope of the line y = -3x + 2?​
allochka39001 [22]

Step-by-step explanation:

Since the slope formula is y = mx +b.

M - slope of line

B - y intercept

y - is the y value of the coordinate, once u plug in x this is your answer

So since m is the slope and the equation is y + -3x +2 the slope of the line is -3

PLEASE HELP!!!! attached photo
alisha [4.7K]

Answer:

(-1, -2.5)

Step-by-step explanation:

The midpoint formula is just basicallyadding both  of the x values and then dividing the sum of them by 2, after that you will be adding both y values and then dividing them by 2, then you will get the midpoint x and y coordinate values. You can look up midpoint formula on google to see how it's actually written. You have to make sure to add correctly when you are using the negative numbers, because they can actually turn the equations into subtraction. Keep in mind, it can beconfusing sometimes when you are working with positive and negative numbers together. So make sure to just double check your work and also to make sure you added correctly.
