Rewrite 2x + 2y = 10 into slope-intercept form:
y(x)= mx + b
2x - 2x + 2y = -2x + 10
2y/2 = (-2x + 10)/2
y = -x + 5
y(x) = -x + 5
Next, we’ll find the value of y when x = -2, 0, 2:
y(-2) = -x + 5
y(-2) = -(-2) + 5
y(-2) = 2 + 5 = 7
Next, we’ll solve for y(0):
y(0) = -(0) + 5
y(0) = 0 + 5 = 5
Finally, we’ll find y(2):
y(2) = -(2) + 5
y(2) = -2 + 5
y(2) = 3
