Find an equation for the linear function which has y-intercept -6 and x-intercept 11

The line crosses the y-axis at -6 and the x-axis at 11. So it has the co-ordinates (0,-6) and (11,0). To go from (0,-6) to (11,0) it goes six up and 11 right, as it is a straight line this is the case all the way along, for every 11 across is goes up by 6. This is the gradient, or angle of rise. The numerical value for this is calculated by , rise being how much it goes up and run being how far it goes right. In this case . The equation of a straight line is y=mx+c m being gradient and c being y intercept. y=x-6

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.
