If a straight line intercepts the π₯-axis at six, zero and intercepts the π¦-axis at zero, five, write the equation of the straight line in two-intercept form.

Letβs recall first the two-intercept form of the equation of a straight line. The two-intercept form of the equation of the straight line that intercepts the π₯-axis at π, zero and intercepts the π¦-axis at zero, π is π₯ over π plus π¦ over π equals one. Weβre told that this line intercepts the π₯-axis at six, zero, so the value of π is six. Weβre also told that the line intercepts the π¦-axis at zero, five, so the value of π is five. Substituting π equals six and π equals five into the two-intercept form of the equation of a straight line gives our answer. π₯ over six plus π¦ over five is equal to one.
