You'll find that y = 4 is the only line that doesn't cross the x axis. Thus y = 4 is the only one that doesn't have an x-intercept.

The answer is y=4. The graph of this equation would just look like a horizontal line that always has a y value of 4.
All the equations have graphs that will pass through the x intercept.

to graph a linear equation it is easiest to get it into the form of y=mx+b. This is called y-intercept form. The first equation has a slope of 3 and a y-intercept of -5, where the line crosses the vertical line of the graph. the second equation has a y-intercept but has no slope. Meaning the line is horizontal starting at 4 on the vertical line. your answer is y=4.

y = 4 is a horizontal line that always at 4. Since it does not cross the x-axis (so y=0), it does not have an x-intercept.

what's up with all of the parentheses? besides, i will take care of them in the order you asked: - For the slope intercept, resolve for y; for this reason, you subtract 4 from the two facets and divide by utilising 2, getting (x-4)/2 = y. on condition that slope-intercept is regularly represented as y = m*x+b, you're greater useful off changing that into the greater time-honored y = (a million/2)*x-2. - Now which you have it in slope-intercept variety, the slope is merely m, which on your case is (a million/2). - The x-intercept is the situation the place the line crosses the x-axis; to discover this place, set y = 0 and resolve the equation for x. for this reason, you get 0 = (a million/2)*x-2, which turns into 2=(a million/2)*x; divide the two facets by utilising (a million/2) to get x = 4. - As with the x-intercept, to discover the y-intercept we could set x = 0 with a view to ensure the place the line crosses the y-axis. This one's greater handy, as we plug in 0 for x ans get y = (a million/2)*0 - 2, leaving us merely with y = -2. i'm hoping you pass returned and attempt to ensure why you get those solutions geometrically, given which you certainly won't ignore them in case you will discover them as pictures on your head extremely than equations on an internet site.
