User: What is the equation of the line whose y-intercept is 3 and slope is 1? y = x - 3 y = x + 3 y = 3x + 1

Weegy: (3x-2) squared is 9x^2 - 12x + 4.

User: What is the equation of the line whose y-intercept is 3 and slope is 1? y = x - 3 y = x + 3 y = 3x + 1

User: If y is 6 when x is 3 and y varies directly with x, find y when x is 8. 4 11 16

Weegy: y=kx...6=k3...6/3=k...k=2...y=(2)(8)...y=16 when x is 8

User: What is the range of the following relation? {(-1, 1), (-2, 2), (-3, 3), (-4, 4), (-5, 5)} A: {-1, -2, -3, -4, -5} B: {1, 2, 3, 4, 5} C: {-1, -2, -3, -4, -5, 1, 2, 3, 4, 5}

Weegy: The range is {1, 2, 3, 4, 5}.

User: Write the equation of the line that has an undefined slope and passes through the point (4, 7). y = 4 x = 4 y = 7 x = 7

Weegy: The only lines with an undefined slope are vertical lines, which are of the form "x = ?". If it passes through (4, 7), then x = 4, so the second answer (x = 4) is correct.

User: What is the equation of a line that has a slope of -5 and passes through the point (0, 2)? y = -5x y = -5x + 2 y = 2x - 5

Weegy: B.y = -5x + 2 - The equation of the line that has a slope of -5 and passes thorugh the point (0,2) is y=-5x+2.

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. k = y/x = 5/2.5 = 2. The equation is y = 2x. When x is 10, y = 2(10) = 20.
