A line passes through the points (7, 3) and (8, 3). What is its equation in slope-intercept form?
Sati [7]

Answer:

y=3

Step-by-step explanation:

The y values are the same, so there cannot be a slope. The (mx) part of y=mx+b is cancelled out, and is left with the b. Since the y value is forever three, the y-intercept will be 3 as well.

Therefore, the slope-intercept equation is

y=3

What is the solution to the system of equations below? y= -4/5 x + and y = –30
Naya [18.7K]

Answer:

x=37.5

Step-by-step explanation:

We need to find the solution to the following system of equations:

y = -\frac{4}{5} x and y=-30

By plugging the value of 'y' into the first equation we have that:

-30 = -\frac{4}{5} x ⇒ 30=\frac{4}{5} x

Solving for 'x' we have:

x=37.5

So, the solution to the system of equation is: (37.5, -30)
