The graph of a linear function is parallel to the graph of the function y = 2x + 5

The graph of a linear function is parallel to the graph of the function y = 2x + 5, draw up a formula for this function if its graph passes point A (1, -2)

In a graph parallel to the graph of this function, y = 2 * x + 5, the coefficient at parameter x will also be equal to 2, and the parameter. which in a given function b = 5, we will search for a parallel function.

And for this we use the coordinates of the point A (1; -2), from which it is clear that x = 1, y = -2. Substitute these values into the equation y = 2 * x + b; -2 = 2 * (1) + b; b = -2 – (1) * (2) = -2 – (2) = – 4.

We got the following equation: y = 2 * x – 4, substitute A (1; -2) to check: -2 = 2 * (1) – 4 = 2 – 4 = -2. Found correctly.
