The answers for the intercepts are as follows:
1. Substituting 0 in for y in the equation y = 3x + 7, we get:
So, the x-intercept for this equation is (-7/3, 0)
2. For the x-intercept, in the equation 3x - 2y = 4, substitute 0 in for y, and solve for x to get:
So, the x-intercept for this equation is (4/3, 0)
For the y-intercept, substitute 0 in for x and solve for y to get:
So, the y-intercept for this equation is (0, -2)
3. Again, to find the x-intercept in the equation f(x) = 2x - 8, substitute 0 in for y (or f(x) in this case) and solve for x:
So, the x-intercept for this equation is (4, 0)
4. For the x-intercept of the equation f(x) = 2x, substitute 0 in for y and solve for x to get:
0 = 2x
0/2 = x
0 = x
So the x-intercept for this equation is (0,0)
For the y-intercept, substitute 0 in for x and solve for y to get:
f(x) = 2(0)
f(x) = 0
So the y-intercept for this equation is (0,0)
