What are the x and y intercepts of 2x + 4y = 8 ?
At the x-intercept, the value of y is zero. To find the x-intercept, 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 y-intercept, the value of x is zero. To find the y-intercept, 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 x-intercept is 4. The y-intercept is 2. Comments are closed.
