Answer:

Step-by-step explanation:
The given equation is:

To find the point where this line intersect the y-axis, we put x=0 into the given equation.
When x=0, we have
.
This implies that; y=5.
The y-intercept is (0,5).
Comparing (0,5) to (0,b), we can conclude that; b=5
Step-by-step explanation:
8. Let's call the number x. We can set up the equation -3x - 5 = -10. Adding 5 to both sides, we have -3x = -5, and when we divide both sides by -3, we have x = 5/3.
9. Again, we'll call the number x. The equation is 2x - 3 = -13. We can write -3 instead of +(-3) because adding a negative number is the same as subtracting. Adding 3 to both sides, we have 2x = -10, and dividing bu -2, we have x = -5. Hope this helps!
The value of x is 23 and the value of y is -6
x = 23
y = -6
You're welcome.
