Question

when graphing y=-2x+10, is it a line that shows only one solution to the equation, all solutions, or shows the y-intercept?

Answer 1

there is always a y-intercept in all graphs.

Explanation:

be it a line graph, quadratic graph or cubic graph. all graphs will definitely have a y-intercept. and in this case, since y=mx + c where c is the y-intercept. the y intercept of this graph is 10
