When y = 7x +4 the y intercept is 4 and the slope is 7
By substitution
There are a couple ways to determine the equation of a line without graphing. How to proceed depends on what you know about the line. Do you know a point, (x1, y1), and slope, m? Then use the point-slope formula, Do you know two points on the line, say (x1, y1) and (x2, y2)? Then use the two-point formula,
Graphing involves plotting points or shapes on a coordinate plane, representing various mathematical relationships. Graphing a line means drawing an infinite straight path extending in both directions, defined by a linear equation. In contrast, graphing a line segment involves drawing a finite portion of a line, characterized by two endpoints, and represents only the points between those endpoints. Thus, while both involve linear relationships, the scope and representation differ significantly.
yes, and the x-axis is horizontal

By substitution
Without the inclusion of an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be a straight line equation

when graphing a line you simply plot the points based on the ordered pairs and connect the dots; there you have a line. An inequality graph refers to the shaded region of the coordinate plane that does not coincide with the line, hence the term, inequality.
You must find the slope, if it is positive, then the line is always increasing. If it is negative, then the line is always decreasing.
line graphing
In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.
