Question

What is the equation in slope-intercept form of the line that passes through the points (0, −4) and (2, 0)?

Answer 1

Answer:

y=2x-4

the slope is 2 and the y-intercept is -4, the equation is

Step-by-step explanation:

m=y2-y1/x2-x1

0-(-4)=4

2-0=2

4/2=2

slope=2

y=mx+b

0=2(2)+b

2*2=4

4-4=0

0-4=(-4)

y-intercept=(-4)

y=2x-4

hope this helps :3

if it did pls mark brainliest

Answer 2

Answer:

$y = 2x -4$

Step-by-step explanation:

Slope intercept form is  $y = mx + b$ where m is the slope and b is the y-intercept.

Slope is $\frac{rise}{run}$ or $\frac{y_2 - y_1}{x_2-x_1}$ in this case = $\frac{0 - (-4)}{2 - 0} = \frac{4}{2} = 2$

Substitute one of the coordinates for x and y. I am going to use (0, -4) so:

$-4 = 2(0) + b\\-4 = 0 + b\\-4 = b$

since m = 2 and b = -4, we can conclude that the equation would be

$y = 2x -4$
