-10x+18y=4 is an equation in the slope-intercept form, where y is the dependent variable, x is the independent variable, -10 is the coefficient of x, 18 is the coefficient of y and 4 is the constant.
This is a Linear equation and it represent a straight line in a two-dimensional coordinate system. The slope of the line is -10/18 or -5/9 and the y-intercept is 4/18 or 2/9.
It is important to note that the equation represents all the points that are on that line, where x and y are coordinates of those points, and for each value of x, there is a corresponding value of y that makes the equation true.
