User: Find the ordered pair solution to the following system of equations (Use any method): 3x – 2y = –1 2x + y = 4 (Points : 5) (2, 1) (1, 2) (1, 1) (2, 2)

Weegy: 6x+18y=6(mul by 3) 6x+4y=20(mul by 2).So sub the 2 eq from 1.Hence 14y=-14.So y=-1 and hence 2x=2+6.So x=4.

Given the function f(x) = - 2x , find the value of f(–1).
Weegy: f(-1) = (-1)^2 - 2(-1) = 3 f(1) = 1^2 - 2(1) = -1 (More)

When f(x) = - 2x , the value of f(–1) is 2.
f(-1) = -2*(-1) = 2.

In the form, y = mx + b, m stands for the slope and b stands for the y-intercept; therefore, in the equation y = 2x + 1,
Slope: 2
y-intercept: 1
