Final answer:
To find y given m = 4, x = 5, and b = 12, use the equation y = mx + b. After substituting the values, we find that y = 32.
Step-by-step explanation:
To find the value of y given that m = 4, x = 5, and b = 12, you would use the equation y = mx + b. Plugging in the given values, we get y = (4)(5) + 12. Calculating this, we get y = 20 + 12, which then simplifies to y = 32. Therefore, if m = 4, x = 5, and b = 12, the value of y is 32.
