The slope-intercept form is expressed as y = mx + b where m is the slope of the line and b is the y-intercept. To be able to write the given information, into this form, we use the point slope form. We do as follows:

<span>y − y1 = m(x − x1)
</span><span>y − 7 = -2(x − 6)
y - 7 = -2x + 6
y = -2x +13 </span>

Slope intercept form: y = mx + b

m = slope

b = y-intercept.

We have m which is -2

y = -2x + b

We need to find the y-intercept so plug 6 for x and 7 for y (6,7)

7 = -2 * 6 + b

7 = -12 + b

19 = b

Now put b in the equation

y = -2x + 19

Answer:

5b=2f

Step-by-step explanation:

Priya uses $7\dfrac{1}{2}$ cups of floor to make 3 loaves of banana bread.

Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour.

To find the relation between b and f, the steps are as follows :

$\dfrac{\text{cups of flour}}{\text{loaves of banana bread}}=\dfrac{7 \dfrac{1}{2}}{3}\\\\=\dfrac{\dfrac{15}{2}}{3}\\\\=\dfrac{15}{2}\times \dfrac{1}{3}\\\\=\dfrac{5}{2}$
