What is the equation of the graphed line written in standard form

Find the slope of the line y =8/9x + 1.

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.

Which linear function represents the line given by the point-slope equation y + 1 = –3(x – 5)?
