Write the equation of a straight line parallel to the graph of the function y = 0.3x and passing through the point (1; -0.7)

From the condition of parallelism of two straight lines, we obtain that the slopes of the graphs are equal:

k1 = k2 = 0.3;

y = 0.3 * x + b – equation of a straight line.

Now we simply substitute the values of the coordinates of the point belonging to the graph of the linear function from the condition of the problem, and we get the equation:

-0.7 = 0.3 * 1 + b;

b = -0.7-0.3 = -1;

y = 0.3 * x – 1 – equation of a straight line.
