Given that the area of the triangle formed by the first-order function y = 2x + B and two coordinate axes is 4, the value of B can be obtained If there is a process, it would be better. I wish the person who answers the question is safe. (the person who answers the question) I speak very accurately! ↖ (^ω^) ↗

When x = 0, y = b
When y = 0, x = - B / 2
Because area = x0 * Y0 = b * (B / 2) * (1 / 2) = B ^ 2 / 4 = 4
So B ^ 2 = 16
B = plus or minus 4
