Describe the meaning of the y-intercept

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

Answer 2

Answer:

Answer:

y-value at intercept = f(0), the value of the function when x = 0

Step-by-step explanation:

The "y-intercept" of a graph (any graph, not just a straight line) is the y-value obtained when x = 0. In other words, the y-intercept is the point at which the graph crosses the y-axis (whose equation is x = 0). Very often the y-intercept represents the initial (beginning) value of functions whose domains include [0, +infinity).

Jack bought a pizza and a drink for $2.65. if the pizza costs a penny more than 3 times the cost of the drink, how much did each cost?

Answers

To get the answer we can prepare equation. Lets assume x its drink.
Finally we get the equation
3x+x+0.01=2.65
4x+0.01=2.65 /-0.01
4x=2.64 /:4
x=0.66 - cost of drink
3x+1 ---- 3*0.66+0.01=1.99 - cost of pizza

66 cents for drink. and 1.99 for the pizza. hope thus helped
