Parallel straight line equations have the same slope but with different y intercepts

Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8).
The equation is x = -7.
Without an equality sign and not knowing the plus or minus values of the given terms of the line which then can't be considered to be a straight line equation. In general for lines to be parallel to each other they will both have the same slope but different y intercepts.
Assuming the equation of the given line is y = 3x + 4, its gradient is 3.Therefore the gradient of the required line is 3. The line passes through (3, 1) and so its equation is y - 1 = 3*(x - 3) = 3x - 9 So y = 3x - 8
Given a triangle and a line, if the line passes through two sides of the triangle parallel to the third side, then it cuts the sides proportionally.l
