22. A line passes through (-6,-1) and (3, 2).
What is the equation of the line?

y = 1/3x + 1 or y = 2 + 1/3(x-3)

Step-by-step explanation: Solve for the slope: (y2-y1) / (x2-x1), in this case, 2 - (-1) / 3 - (-6) = 3/9 = 1/3. Then, write it in point-slope form:

y = y1 + b(x-x1), in this case,

y = 2 + 1/3(x-3) or y = -1 + 1/3(x-(-6). To convert to intercept form (y = a +bx), distribute the 1/3 so that it's y = 2 + 1/3x - 1, then combine like terms to get y = 1 + 1/3x.

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

.5 lb

step-by-step explanation:

12 in / 6 in =2 in

.25 x 2 = .5 lb
