Write an equation in slop-intercept form the line with slope 1/4 and y-intercept -7

Licemer1 [7]

When you write an equation in the slope-intercept form

$y=mx+b$

the two coefficients m and b represent, respectively, the slope and the intercept.

So, in your case, m=1/4 and b= -7, which leads to the equation

$y=\dfrac{1}{4}x-7$

What is the area of the figure?

uysha [10]

I think it'd be 10in. If you cut it into three parts, where the bottom is sectioned off from the other two rectangles, the two rectangles on the side both have an area of 3in, so together they'd be 6in. The rectangle on the bottom has a length of 4 and a width of 1, so it'd be 4in... add those together and get 10in. Hope this helps

The depth of a lake, d, varies directly with r, the amount of rainfall last month. if k is the constant of variation, write an e

irina1246 [14]

Answer:
d = kr

Explanation:
We know that the depth (d) varies directly with the amount of rain (r).
This means that as the amount of rain increases, the depth increases and vice-versa.
The depth would depend on r multiplied by a constant of variation (k)

Translating this into equation, we would get the following:
d = kr

Hope this helps :)
