Find the equation of a line that passes through these two points

Sati [7]

Answer:

y = -2x + 2

Step-by-step explanation:

The equation of a line is y = mx + b.

First we want to find m, the slope. We can used the coordinates to do so: $m = \frac{6-(-4)}{-2-3}\\m = \frac{10}{-5}\\m = -2$

Now we know that the equation is y = -2x + b. We can plug in the coordinate (3, -4) to find b.

$y = -2x + b\\-4 = -2(3) + b\\-4 = -6 + b\\b = 2$

So the equation is y = -2x + 2.

Abit is planning a birthday party for his granddad. He bought a cake for $18\$18$18dollar sign, 18. He also wants to buy some ba

Arturiano [62]

Answer:

$1.00

Step-by-step explanation:

Total Budget = $35

Cake Spent = $18

Remaining Money = 35 - 18 = $17

Since, each balloon is worth $4, to find how many balloons he will get with remaining money ($17), we divide the the remaining money by price of each balloon:

17/4 = 4.25

We can't have fractional balloons, so Abit can get 4 balloons, MAXIMUM.

4 balloons cost = $4 per balloon * 4 = $16

So, from $17 if he spends $16 for balloons, he will have left:

$17 - $16 = $1.00

Which of the following ordered pairs represents a solution to the linear inequality y<6x-4? A. (0,3) B.(0,11) C. (0,-5) D.(0,

son4ous [18]

Answer:

Option C. (0,-5)

Step-by-step explanation:

See the attached figure.

As shown the shaded area represents the solution of the given inequality:

y < 6x - 4

The given options are the points:

A. (0,3) B.(0,11) C. (0,-5) D.(0,4)

Comparing the given points to the graph.

So, the point that will lie at the shaded area represent solution to the linear inequality.

So, point (0,-5) is a solution to the linear inequality.

The answer is option C. (0,-5)

Note: the line y = 6x-4 is graphed using the table on the graph.

Write an equation of the line that passes through the given points. question (-4, 3), (O, -10)

expeople1 [14]

Answer:

$Y=(\frac{4}{7}) x+2$

Step-by-step explanation:

$Y=mx+b$

$M=\frac{x2-x1}{y2-y1}$

$M=\frac{0-(-4)}{-10-3}$

$M=\frac{-4}{-7}$

$Y=(\frac{4}{7}) x+2$
