Write the equation of the line that passes through the given points. (0, -1) and (-5.-9)

Elis [28]

Answer:

$y=\frac{8}{5}x-1$

Step-by-step explanation:

Recall:

Slope -> $m=\frac{Rise}{Run}=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}$
Slope-intercept form -> $y=mx+b$
Y-intercept -> $b$

Given:

$(x_1,y_1) = (0,-1)$
$(x_2,y_2) = (-5,-9)$

Slope calculation:

$Slope=\frac{y_2-y_1}{x_2-x_1}=\frac{-9-(-1)}{-5-0}=\frac{-9+1}{-5}=-\frac{8}{5}=\frac{8}{5}$

Y-intercept calculation:

$y=\frac{8}{5}x+b$

$-1=\frac{8}{5}(0)+b$

$-1=0+b$

$-1=b$

Final equation:

$y=\frac{8}{5}x-1$

HELPPPPPPP MULITPLY AND FIND OUT IF ALL HESE ARE CORRECT IF THEY'RE NOT TELL ME AND PLS GIVE ME THE ANSWERS FOR QUESTION 4

pashok25 [27]

Answer:

Ok so the first one is right and the second one is right for the first question

For the second Question your also right

Step-by-step explanation:

Question 3

12/7 is greater than 6/13 and it's asking what numbers would be incorrect meaning less than 6/13 (unmark 12/7)

1/10 is correct since 6/13 is greater than 3 / 65 (It's what you get when you multiple 1/10 with 6/13)

Unmark 4/3

Unmark 3

and 13/13 is just equal to 6/13 (leave unmarked)

Explain how to write a function rule from the table below. Then write a function rule.

Brut [27]

To find the slope you do y1-y2/x1-x2

To find the y intercept you look at when x is zero what is y.

Equation is y=-1/2x -2
