What are the x and y intercepts of 2x + 4y = 8 ?
At the xintercept, the value of y is zero. To find the xintercept, just substitute zero in for y.
2x + 4y = 8 2x + 4(0) = 8 {substituted zero for y} 2x = 8 {multiplied 4 by 0} x = 4 {divided each side by 2} At the yintercept, the value of x is zero. To find the yintercept, just substitute zero in for x. 2x + 4y = 8 2(0) + 4y = 8 {substituted zero for x} 4y = 8 {multiplied 2 by 0} y = 2 {divided each side by 4} The xintercept is 4. The yintercept is 2. Comments are closed.
