4. the distance between singapore and sydney is 6300 km correct to the nearest 100 km. a businessman travelled from singapore to sydney and then back to singapore. he did this six times in a year. between what limits is the total of distance he travelled?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

the correct answer is a.) bc< mn 5 stars if this you : )
