Answer:

y = 3x - 6

Step-by-step explanation:

(1, -3) (7, 15)

Step 1. Find the slope

Slope = 3

Step 2. Create the equation of the slope then use a point and plug it in as terms of x and y with a y-intercept at the end

y = 3x + b

(15) = 3(7) + b

15 = 21 + b

15 - 21 = b

b = -6

Thus, the equation of the line is y = 3x - 6

PLEASE ANSWER I NEED HELP!!..
nikitadnepr [17]
Please don't post masses of questions all at once.  1-2 problems per post would be more realistic and fairer to others who need help.

Regarding   <span>x-2/5 = 1/5

We are to solve for x.   To do this, let's remove the fractions by mult. all 3 terms by 5.  Then 5x - 2 = 1, or 5x = 3.

Dividing both sides by x, we get x = 3/5 (answer).  Check this by subst. 3/5 into the original equation.</span>

A) 1.4x -0.64 = 0.2
its same like given y=1.4x-0.62
means that y=0.2
find a point on the line with y-coordinate 0.2. i think x-coordinate of this point is 0.6.

means that x = 0.6

b) -1.2=1.4x - 0.64
here y = -1.2
find on the line point with y-coordinate -1.2 and tell what is it's x-coordinate. thats' the answer.

volume of the 2 stacked granola bars = volume of one granola bar x 2

volume of one granola bar = Volume of a prism = base area x height

5 x 55 x 30 x 2 = 15,000
