write an equation in point-slope form of the line that passes through the (7,-4) and has a slip of m=-6?
Leokris [45]

Answer:

y+4=-6(x-7)

Step-by-step explanation:

Point slope form is giving by the equation

y - y = m (x - x)

M being the slope and y and x being points

All you have to do is plug in your slope and point:

(y + 4) = -6 (x - 7)

Write an equation of the line that passes through (2,7) and is parallel to the line shown ( please help !! )
Anna007 [38]

Answer:

y=2x+3

Step-by-step explanation:

We will first need to determine the slope of the line shown.

We know that it passes through the two points (-2, -2) and (1, 4).

Thus, we can use the slope formula to find the slope between the two points:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Let (-2, -2) be (x₁, y₁) and let (1, 4) be (x₂, y₂). Substitute:

\displaystyle m=\frac{4-(-2)}{1-(-2)}=\frac{6}{3}=2

Hence, the slope of the original line was 2.

Since we want the new line to be parallel, the slope of the new line must also be 2.

We know that the slope is 2 and it passes through the point (2, 7).

So, we can use the point-slope form:

y-y_1=m(x-x_1)

We will substitute 2 for m. We will also let (2, 7) be (x₁, y₁). Substitute:

y-7=2(x-2)

Solve for y. Distribute the right:

y-7=2x-4

Add 7 to both sides. Hence, our equation is:

y=2x+3

In 2015 Organization raised $543. The following year they raised $89. How many money did they raised over the two period? Show h
galina1969 [7]

Answer:

632

Step-by-step explanation:

So you take one from the 3 to make it 2 and add it on to 89 to make 90. next take 10 from 542 and add it to the 90, you get 100. Then 532 + 100 = 632

Hope this helps
