Answer:
4
Step-by-step explanation:
The equation of the line is written in the slope-intercept form, which is: y = mx + b, where m represents the slope and b represents the y-intercept. In our equation, y = − 7 x + 4 , we see that the y-intercept of the line is 4.

Answer:
5652 cm³
Step-by-step explanation:
V = 2πr² + 2πrh
= (2 × 3.14 × 3.14 × 20 ×20) + (2 × 3.14 × 20 × 25)
= 2512 + 3140
= 5652 cm³
Y = x - 9 meets the y-axis at (0,-9)
y = -2x - 3 meets the y-axis at (0,-3)
This is because for every linear equation, there is a formula corresponding to it as y=mx + c, where (0,c) is where it meets the y-axis. As we assign the value of 0 to x, only c will be left to equal y, being the intercept.
