Answer:

y=3/5X+5/6

Step-by-step explanation:

Y=ax+b

(-4;-3) (6:3)

-3=-4a+b

3=6a+b

3-6a=-3+4a

6=10a

a=6/10=3/5

Steven has $25 dollars. He needs to set aside $10.00 to pay for his lunch next week. If peanuts cost $0.38 per package including

Tanzania [10]

39 packages.

Because he sets aside 10, he has $15 left.
15 divided by $0.38 = 39.4736, however he cannot but a fraction of a package so you round down to 39.

Complete the equation of the line through ( − 1 0 , − 7 ) (−10,−7) and ( − 5 , − 9 ) (−5,−9).

The point-slope form:

$y-y_1=m(x-x_1)$

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-10, -7) and (-5, -9). Substitute:

$m=\dfrac{-9-(-7)}{-5-(-10)}=\dfrac{-9+7}{-5+10}=\dfrac{-2}{5}=-\dfrac{2}{5}$

$y-(-7)=-\dfrac{2}{5}(x-(-10))$

$\boxed{y+7=-\dfrac{2}{5}(x+10)}$ point-slope form

$y+7=-\dfrac{2}{5}(x+10)$ use distributive property

$y+7=-\dfrac{2}{5}x-4$ subtract 7 from both sides

$\boxed{y=-\dfrac{2}{5}x-11}$ slope-intercept form

$y=-\dfrac{2}{5}x-11$ multiply both sides by 5

$5y=-2x-55$ add 2x to both sides

$\boxed{2x+5y=-55}$ standard form
