D. 5 **Weegy:** A line passes through the point (0, -3/2) and has a slope of 1/2. What is the equation of the line? A) y = 1/2 x - 3/2 **User:** What is the equation of a line, in general form, with a slope of -2 and a y-intercept of 8?
A. x + 2y - 8 = 0
B. 2x + y - 8 = 0
C. 2x - y + 8 = 0 **Weegy:** Choice B is correct.
*you can set up slope-intercept immediately; the equation is y = -2x + 8. Putting all terms on one side, you get 2x + y - 8 = 0 **User:** What is the equation of the line, in general form, that passes through the point (1, 1) and has a y-intercept of 2.
A. x - y + 2 = 0
B. x + y - 2 = 0
C. x - y - 2 = 0 **Weegy:** C.x - y - 2 = 0
**User:** What is the equation of the line whose y-intercept is 3 and slope is 1?
A. y = x - 3
B. y = x + 3
C. y = 3x + 1 **Weegy:** The answer is B=3/2. To find the slope of this line, first rearrange the equation to slope intercept form which is y=mx+b where m is the slope. [ After rearranging it, we get 2y=3x- 4.......divide by 2 to get y by itself......which in turn leaves us with y=1.5x- 2........therefore the slope is 1.5, or 3/2. ] **User:** What is the equation of a line, in general form, with a point (-3, 0) and an undefined slope?

If y is 5 when x is 2.5 and y varies directly with x, the equation is y = kx where k is the constant. With given information, k = y/x = 5/2.5 = 2. The equation is y = 2x. when x is 10, y = 2(10) = 20.
