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:

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).

Answer:-6,5

Step-by-step explanation:the first digit is your x and the second is your y so we go 6 back from the origin and 5 up from zero and we get -6,5. Also you always do x first

A ladder 3m long leans against a wall. It reaches 2m up the wall. What angle does the ladder make with the ground?

Here. I drew a triangle just for this problem. :) You can find it in attachments.

To find the angle, we must use the sine function. To find the angle, we must know the sine of the angle first. The formula for the angle we are trying to find is:

(Forgot to mention, let the angle = x)

$sinx= \frac{2}{3}$

= $sinx = 0.3333....$

Knowing this, we can now derive that:

$x=sin^{-1}0.3333$

Using our scientific calculators, we find that:

$x=19.47122$ °

Which is our final answer. You may round accordingly.

Thank you, and I hope that helped. :)
