Point slope form of the equation can be written as follows
y - y₁ = m (x - x₁)
y and x are the 2 variables , m is the slope and x₁ and y₁ are the respective coordinates for the given point
in this format a point of a line and the slope of the line are given. using this information we can write down the point - slope formula for the graph
since a point has been given we know the x₁ and y₁ coordinates.
These are the coordinates of the given point (-1,6)
x₁ = -1
y₁ = 6
slope has been given as -3, m = -3
substituting these values in the formula, 
y - y₁ = m (x - x₁)
y - 6 = -3 (x - (-1))
y - 6 = -3 (x + 1)
answer is B.

Answer:

The correct answer is option B.

Step-by-step explanation:

Two point form of the equation:

(y-y_1)=\frac{y_2-y_1}{x_2-x_1}\times (x-x_1)

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

(y-y_1)=m\times (x-x_1)

A line passing through the point (-1,6) with slope ,m = -3.

The equation of the line will be:

y-6=(-3)(x-(-1))=(-3)(x+1)

Hence, the correct answer is option B.

Part 1:
180 = 5p+98 + 9p-2
180 = 14p + 96
84 = 14p
6 = p

part 2:
angle S will be the same as angle Q, so:
9p-2
9(6)-2
54-2

I have to find slope-intercept equation
adoni [48]

Answer:

y = 4x - 9

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

the y-intercept is when the line crosses the y axis, and in this case we can see it at "-9"

The slope we can do rise over run "r/r" ot "y/x"

r/r = 4/1 = 4

The line is positive since its going up

y = 4x - 9

Hope this helped!

Answer:

Yes

Step-by-step explanation:

Divide the number of states by 6 then find what 5 of those 6groups would be...

63 divided by 6 is 10.5 & 10.5 times 5 is 52.5 that means at least 53 states have to approve. 59 is greater then 53
