what is the equation of a line that passes through the points (0,5) and (4,8)? write the answer in slope-intercept form.

Sergio039 [100]

Answer:

Step-by-step explanation:

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (4, 8) and (0, 5) → b = 5.

Calculate the slope:

$m=\dfrac{5-8}{0-4}=\dfrac{-3}{-4}=\dfrac{3}{4}$

Therefore we have the equation of the line:

$y=\dfrac{3}{4}x+5$

What is the most logical first step in solving the equation x2 + 6x +9 = 10?

Shalnov [3]

Answer:

Step-by-step explanation:

The logical step is to <u>factorize the left side of the equation</u>, which becomes:

(x + 3)² = 10

Then, you can take the square root on both sides.

x + 3 = ±√10
x = ±√10 - 3

Not asked, but good to understand the procedure regardless.
