Write the equation of the line that passes through points (-4, 5) and (0,13) in slope-intercept form.

LiRa [457]

Answer:

The answer is

$y = 2x + 13$

Step-by-step explanation:

Remember:

$Slope-intercept form: \: \\ y = mx + b \\ \\ m = slope \\ b = y - intercept$

$M = \frac{y_2 - y_1}{x_2 - x_1}$

First: Find the slope.

$M = \frac{13 - 5}{0 - ( - 4)} = \frac{8}{4} = 2$

Second: Solve for the y-intercept

$y = mx + b \\ 5 = 2( - 4) + b \\ 5 = - 8 + b \\ \frac{+ 8 = + 8 \: \: \: \: \: \: \: \: }{13 = b}$

Third: Plug in.

$y = mx + b \\ y = 2x + 13$

lapo4ka [179]

Hi there!

To solve this problem, first we need to convert everything into feet.

1.5 mi = 7920 ft

Since
7920 is greater than 3520,

Ashley lives closer to the school.

Hope this helps!

A had $360 more than B. When A spent $144 and B spent half of his money, A had 6 times as much money as B, Find the ratio of the

Karolina [17]

Answer:

13:3

Step-by-step explanation:

A=x B=y

first; x= 360+y

later;x= 216+y

A:B

216+y: 1/2y = 6: 1

216+y/y÷2 =6/1

216+y = 3y

y = 108

first; x =360+y

360 +108

468

A:B = 468:108
