To determine the total variation in water level, multiply 1.8 mm/year by 2.2 years. The exact answer is 3.96 mm/year. Use rounding to check the answer by using the problem 2(2) =4. 4 is close to 3.96.

A line intersects the points (0,-4) and (1,2) what is the slope intercept equation for this line?

agasfer [191]

Answer:

$y=6x-4$

Step-by-step explanation:

First we have to know how to write a equation in Slope-Intercept Form!

Slope-Intercept Form: $y=mx+b$

where y = y axis, m = slope, x = x intercept and b = y-intercept

Now start by solving the slope

To find the Slope, you must find two points

Two points will be: $(0,-4)$ and $(1,2)$

Then use the Slope-Formula to identify the slope

$m=slope$

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

$m=\frac{2--4}{1-0}$

$m=\frac{6}{1}$

$m=6$

The Slope is 6

The y-intercept is already given by the point (0, -4)

Note: (this goes to this situation because the point has a 0 of x intercept)

What is the slope of the line whose equation is 12 = 4x – 6y?

timama [110]

$12=4x-6y \\ -4x -4x \\ 12-4x=-6y \\ /-6 /-6 \\ -2+ \frac{2}{3}x=y$
therefore the slope of the line is $\frac{2}{3}$
