x-intercept = - 6
y-intercept = -5
Explanation:
This is the equation of a line.
When the line crosses the x-axis,#color(blue)"x-intercept"# , the value of the y-coordinate will be zero. Substituting y = 0 into the equation and solving for x gives the x-intercept.y=0 : 5x+0=-30
#rArrx=-6" x-intercept"# Similarly when the line crosses the y-axis,
#color(blue)"y-intercept"# , the value of the x-coordinate will be zero.x = 0 : 0 + 6y = - 30
#rArry=-5 " y-intercept"#
