Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
Slope = 4
If the equation is x+4 the slope is 1. If the equation is 4x than the slope is 4.
-3
There is a standard equation for a straight line. It is y = mx + b. m is the slope and b is the y-intercept (when x = 0). In the question m = -4 and is therefore the slope of the line represented by the equation y = -4x + 7.
