Given the graph above find an equation for the graph and write your anwser in slope intercept form
lys-0071 [83]

<u>Given:</u>

Given that the graph of a linear function.

We need to determine the equation of the graph in slope intercept form.

<u>Slope</u>:

Consider any two coordinates from the equation of the line to determine the slope.

Let the two coordinates are (-4,3) and (4,-1)

The slope can be determined using the formula,

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

Substituting the coordinates in the above formula, we get;

m=\frac{-1-3}{4+4}

m=\frac{-4}{8}

m=-\frac{1}{2}

Thus, the slope of the equation is m=-\frac{1}{2}

<u>Value of y - intercept:</u>

The value of y - intercept is the value of y when x = 0.

Hence, from the graph, it is obvious that the value of y when x = 0 is 1.

Hence, the value of y - intercept is 1.

Thus, y - intercept is b=1

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

y=mx+b

Substituting the slope m=-\frac{1}{2} and the y - intercept b=1

Thus, we get;

y=-\frac{1}{2}x+1

Thus, the equation of the line is y=-\frac{1}{2}x+1

The cash price of a television is $580.
Drupady [299]

Answer:

n=25% or 0.25

Step-by-step explanation:

865= 580(n%)+ 6(120)

865= 580 (n%) +720

865-720= 145

145= 580(n%)

divide both by 580, you get 0.25=n%
