Final answer:
The y-value for the equation y = 5x + 2 when x is 1 is 7. Therefore, the second point to be plotted on the graph would be at (1, 7).
Step-by-step explanation:
To draw a line for the equation y = 5x + 2, you have correctly stated that a first point can be plotted at an x of 0, which gives a y of 2. Let's determine the y-value when x is 1. Plugging 1 into the equation for x, we get:
y = 5(1) + 2
y = 5 + 2
y = 7
So, when x is 1, y is 7, and the second point that can be drawn on the graph is at (1,7).
The options given in the question are:
a. 3
b. 5
c. 7
d. 9
The correct answer is 'c. 7' for the y-value when x is 1.
