What you have to for this problem is combine like terms.

So for the equation 7.21x+1.12−4.53x, all you have to do is subtract 4.25x from 7.21x.

The answer you should get is, 2.68x+1.12.

I hope that helps you!

A line passes through the points (1, –6) and (4, 3).
Ivanshal [37]

Answer:

y = - 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, - 6) and (x₂, y₂ ) = (4, 3)

m = \frac{3+6}{4-1} = \frac{9}{3} = 3

y = 3x + c ← is the partial equation

To find c substitute any of the 2 points into the partial equation

Using (4, 3), then

3 = 12 + c ⇒ c = 3 - 12 = - 9, hence

y- intercept c = - 9 ⇒ (0, - 9 )
