Answer:

y=4

Step-by-step explanation:

Since the slope is constant, and the only y value for each x value is 4, then the equation is y=4.

Answer:

y=4

Step-by-step explanation:

It's 4 on the y axis! There is no line intersecting with points on the x axis.

This type of slope is often confused with vertical lines! Vertical lines are always undefined. Horizontal lines are simply 0. You cannot use RISE/RUN, because you can only go one way on the line, right/left.

I hope this helps and made sense!

y = - $\frac{3}{4}$ (x - 5)² + 4

the equation of a quadratic in standard form is

y = a(x - h)² + k ( where (h , k ) are the coordinates of the vertex and a is a multiplier )

given vertex = ( 5, 4 ) then

y = a(x - 5)² + 4 ( to find a substitute (7 , 1 ) into the equation )

1= 4a + 4

4a = - 3 ⇒ a = - $\frac{3}{4}$

y = - $\frac{3}{4}$ (x - 5)² + 4 ← ( in vertex form )

Answer: C) angle 2 and angle 7

Imagine the parallel lines form the boundaries of river. Angles 3, 4, 5 and 6 are considered interior angles as they are in the river. Angles 1, 2, 7, 8, 9 and 10 are exterior because they're outside the river.

Angles 2 and 7 are on opposite sides of the transversal cut that I've highlighted in red (see diagram below). So that's why they're considered alternate. Combine "exterior" and "alternate" to get "alternate exterior"
