The graph of the line y = 4 is a a) vertical line with a slope of zero. b) horizontal line with a slope of zero. eliminate c) vertical line with an undefined slope. d) horizontal line with an undefined slope.

B) horizontal line with a slope of zero.

Step-by-step explanation:

∵ The equation of the type y = mx + c is always a straight line having the slope m,

Also,

Where,

= angle from the positive x-axis,

If m = 0, ⇒

i.e. line is parallel to x-axis or a horizontal line,

if m = ∞ ⇒

i.e. line is perpendicular to x-axis or vertical,

Here, the given line,

y = 4,

⇒ y = 0x + 4

By comparing,

m = 0,

⇒ It is a horizontal line with a slope of zero.

Hence, OPTION B is correct.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
