What is an equation in slope-intercept form of the line that passes through the points (−2, −2) and (1, 7)? A.y = 4x + 3 B.y − 7
antoniya [11.8K]

Answer:

C.y = 3x + 4

Step-by-step explanation:

We have two points, so we can find the slope

m = (y2-y1)/ (x2-x1)

   = (7--2)/ (1--2)

   = (7+2)/(1+2)

    = 9/3

    =3

The slope is 3

We can find the point slope form of the line

y-y1 = m(x-x1)

y-7 = 3(x-1)

Distribute

y-7 =3x-3

Add 7 to each side

y-7+7 = 3x-3+7

y = 3x+4

This is in slope intercept form (y=mx+b)

Which equation represents a line that has a slope of -1/2 and passes through point (4, –5)?
Wewaii [24]
Y=-1/2x-3

You can rewrite the equation “y=mx+b” and fill in what you know. So your equation would look like y=-1/2x+b when filling in what you know. Now you can take the (x,y) coordinates that you were given and plug them into the equation and solve for b. So now it would be -5=-1/2(4)+b

Uncle Joe is cutting boards for bookshelves. If he begins with 9 feet of wood, how many shelves will he cut if each one is 1 1/2
kherson [118]

To get the answer, you divide the length of the board by the size of the pieces wanted, so the equation you get is

9/1.5 = 6

So you can get six 1.5in shelves from a 9ft board
