Final answer:
The y-intercept of the equation y=2x-3 is the constant term -3. Therefore, the correct answer is b) -3, which is the value of y when x is 0.
Step-by-step explanation:
The y-intercept of a linear equation in the form of y = mx + b is represented by b. Therefore, when looking at the equation y=2x−3, the y-intercept is the constant term, which in this case is −3. So, when x is 0, y will be −3. Hence, the correct option for the y-intercept of the equation y=2x−3 is b) −3.
To find the y-intercept, you can also plug in x = 0 into the equation and solve for y, which would yield y = (2*0) - 3, simplifying to y = −3.
The y-intercept, or the value of y when x is zero, can be determined by looking at the equation of the line. In the equation y = 2x - 3, the y-intercept is represented by the constant term -3.
Therefore, the correct option for the y-intercept of the equation y = 2x - 3 is (b) -3.
