What is the equation of a line that passes through (4, 3) and has a slope of 2?

1 answer:

3 0

So right of the bat the equation we know from what's given is y = 2x (+b)
we gotta find out what b is
so we plug the coordinate in
3=8+b.
b=-5
so we put all the pieces back together to get
y = 2x - 5

Solve for x, −2 (4x+4) −3x − 2 = 34 help needed, thanks!

Hey there!

The answer to your question is $-2 \frac{3}{11}$

$-2(4x+4) - 3x -2= 34$ Write the equation

$-8x - 8 - 3x - 2 = 34$ Distribute -2

$-11x-10 = 34$ Combine like terms

$-11x = 24$ Add 10 to both sides

$-2 \frac{3}{11}$ Divide both sides by -11

Hope it helps and have a great day!

what is the equation in slope intercept form of the line that passes through the point (-4,47) and (2,-16)

Vilka [71]

The slope-intercept form:

$y=mx+b$

The formula of a slope:

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

We have the points (-4, 47) and (2, -16). Substitute:

$m=\dfrac{-16-47}{2-(-4)}=\dfrac{-63}{6}=-\dfrac{63:3}{6:3}=-\dfrac{21}{2}$

Therefore we have:

$y=-\dfrac{21}{2}x+b$

Put the coordinates of the point (2, -16) to the equation:

$-16=-\dfrac{21}{2}(2)+b\\\\-16=-21+b\qquad\text{add 21 from both sides}\\\\5=b\to b=5$

Answer: $\boxed{y=-\dfrac{21}{2}x+5}$
