What is the equation of the line with an x-intercept of -1 and a y-intercept of 2? **Weegy:** With that information, you know that two points on the line at (-5,0) and (0,-2).
Now you find the slope between those two points:
(-5-0)/(0-(-2)) = -5/2... Since now you know the slope, the equation would be y=-5/2x-2
**User:** Find the common difference of the sequence shown.
, , , , ... **User:** If f(x) = 3x2 - x, find f(-2). **Weegy:** f(x) = 3 * 2 + -1x
Multiply f * x
fx = 3 * 2 + -1x
Multiply 3 * 2
fx = 6 + -1x
Solving
fx = 6 + -1x
Move all terms containing f to the left, [ all other terms to the right.
Divide each side by 'x'.
f = 6x-1 + -1
Simplifying
f = 6x-1 + -1
Reorder the terms:
f = -1 + 6x-1 ] **User:** What is the equation of the line that passes through (-3, -1) and has a slope of ? Put your answer in slope-intercept form. **Weegy:** y= -(3/5 )x - 12 **User:** The cost to mail a package is $7 for the first 2 pounds and 30 cents for each additional ounce.
Which of the following functions represents the cost to mail a package if x is the number of ounces over 2 pounds? **Weegy:** Yes, but do you have a question? Do you have a package of a certain weight? If so, you have to tell me what it weighs so I can tell you the cost! **User:** Which of the following represents 3x - 5y + 10 = 0 written in slope-intercept form? **User:** Which of the following represents x = y written in general form?
**User:** What is the equation of the line that passes through (4, -1) and (-2, 3)?
**Weegy:** The equation of the line that passes through (4, -1) and (-2, 3) is y = 5/3 - (2 x)/3 **User:** If y is 5 when x is 2.5 and y varies directly with x, find y when x is 10. **User:** The slope of a line is -. Find the slope of a line that is perpendicular to this line. (More)

f(x) = 3x^2 - x,

f(-2) = 3(-2)^2 - (-2) = 12 + 2 = 14

f(-2) = 3(-2)^2 - (-2) = 12 + 2 = 14
