Determine the slope intercept form of the linear equation from its graph.​
Vlad1618 [11]

Given:

The graph of linear function.

To find:

The slope intercept form of the linear equation from the given graph.

Solution:

The slope intercept form of a linear function is:

y=mx+b

From the given graph it is clear that the graph passes through the points (1,300) and (4,800).

The equation of line is

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

y-300=\dfrac{800-300}{4-1}(x-1)

y-300=\dfrac{500}{3}(x-1)

y-300=\dfrac{500}{3}x-\dfrac{500}{3}

Adding 300 on both sides, we get

y=\dfrac{500}{3}x-\dfrac{500}{3}+300

y=\dfrac{500}{3}x+\dfrac{900-500}{3}

y=\dfrac{500}{3}x+\dfrac{400}{3}

Therefore, the required equation is y=\dfrac{500}{3}x+\dfrac{400}{3}.

Since we are given that m is equivalent to 15 we can plug it into the Area equation given to us like so:

Area = πm²

Area = π15²

Area = π225

The lines s and t intersect at point R.<br><br> What is the value of y?<br><br> y = ____
ozzi
Assuming that the angles are congruent, then y = 29.
4y - 8 = 79 + y
4y = 87 + y             Add 8 to both sides
3y = 87                  Subtract y from both sides
y = 29
