To find the x-intercept, put 0 in for y:
6x + 6y = 30
6x + 6(0) = 30 {substituted 0 in for y}
6x = 30 {multiplied 6 by 0}
x = 5 {divided both sides by 6}
x-intercept is 5 {the line crosses the x-axis at 5}
To find the y-intercept, put 0 in for x:
6x + 6y = 30
6(0) + 6y = 30 {substituted 0 in for x}
6y = 30 {multiplied 6 by 0}
y = 5 {divided both sides by 6}
y-intercept is 5 {the line crosses the y-axis at 5}
graph B.) {has x-intercept of 5 and y-intercept of 5}
