Ok y is your y value from any point on the graph m is your slope x is the x value of any point from the graph and b is your y intercept that is where the line cross in the y line that is the vertical line in the graph

Answer:

As simple as possible, it's a form of linear equations.

Step-by-step explanation:

The formula, y = mx + b, can be dissected to get the slope and y-intercept of a linear equation where:

m = slope

b = y-intercept

(x and y can be substituted for any point)

Find the equation (in terms of x ) of the line through the points (-4,-4) and (2,4)

Greeley [361]

Answer:

$y=\frac{4}{3}x+\frac{4}{3}$

Step-by-step explanation:

Let $(x_1,y_1)\rightarrow(-4,-4)$ and $(x_2,y_2)\rightarow(2,4)$ :

Determine slope

$m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{4-(-4)}{2-(-4)}\\ \\m=\frac{4+4}{2+4}\\ \\m=\frac{8}{6}\\ \\m=\frac{4}{3}$

Use either coordinate point to find "b", the y-intercept

$y=mx+b\\\\4=\frac{4}{3}(2)+b\\ \\4=\frac{8}{3}+b\\ \\\frac{4}{3}=b$

Final Equation

$y=\frac{4}{3}x+\frac{4}{3}$
