Which function rule describes the number of centimeters y as a function of a number of millimeters x?
y = x/10
Which function rule describes the number of centimeters y as a function of a number of millimeters m?
Y(m) = 10 * m or M(y) = y / 10
What graph displays the solution to -x plus 2 is greater than -8?
-6
Write an equation for the function describe by this rule the value of y is 10 times greater than the value of x.?
10y = x ======
Graph the line described by the equation -x plus 5y equals 10?
Simplest way to graph a line like this is on a normal x-y axis. (y vertical, x horizontal) Two methods for drawing the graph # Use the equation to find the value of y when x is zero, and the value of x when y is zero. Plot the two points on the graph (the will be on the axis lines). Then draw a straight line through them. ---- # Rearrange the equation to find y in terms of x e.g. in the form y = mx +c where m and c are numbers. Plot the point (0,c) and then plot another point say at x = 1 (1,m+c). Then draw a straight line through both points. In is example: -x + 5y = 10 when x = 0, 5y = 10 or y = 2 when y = 0, -x = 10 or x = -10 plot the two points (0,2) and (-10,0) and then draw a straight line between them. Sometimes its hard to do this method as if your axis don't go up to -10 the graph will be hard to draw. or => -x+5y = 10 => 5y = x + 10 => y = x/5 + 1/2 plot (0,1/2) and say (1,7/10) and draw the straight line through those points
