Graph the line y=-x+6

1 answer:

5 0

To graph a line, first, we need to plot out values. Let’s find a few: if y is 2, -x would be 2-6, and x would be 4. If y is -2, x would be 8.

Now, all you have to do is put a few more of those points on a line graph and connect them.

Good luck!

A line goes through the points (4, 5) and (2, -6). Write the equation of the line in point-slope

Lerok [7]

Answer:

m (slope) = $\frac{11}{2}$

Step-by-step explanation:

point-slope form: m= $\frac{y2-y1}{x2-x1}$

(4, 5) (2, -6)

x1 y1 x2 y2

-------------------

$\frac{-6 - 5\\}{2 - 4}$ = m

-6 - 5 = -11

2 - 4 = -2

m = $\frac{11}{2}$

Write an equation in point-slope form of the line that passes through the point (9,0) and has a slope of m=-3 .

aksik [14]

Answer:

$y = - 3x + 27$

Step-by-step explanation:

The standard form for the equation of the line is

$y = mx + c$

Recall that:

$y = 0 \: \: \: x = 9 \: \: \: m = - 3 \\ y = mx + c \\ 0 = - 3(9) + c \\ 0 = - 27+ c \\ 27 = c$

Therefore the equation of the line is:

$y = mx + c \\ y = - 3x + 27$

How to solve −3/4n≤3.

mars1129 [50]

Answer:

n ≥ -4

Step-by-step explanation:

-3/4n ≤ 3

-4/3(-3/4n) ≤ 3(-4/3)

n ≥ -12/3

n ≥ -4

CHECK:

correct

-3/4(-4) ≤ 3

12/4 ≤ 3

3 = 3

correct

-3/4(5) ≤ 3

-15/4 ≤ 3

-3.75 < 3

incorrect

-3/4(1) ≤ 3

-3/4 is not ≤ 3
