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:

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

What is the y-intercept of the line shown? A. O B. 1 C. 3 D. 3.5

Lelechka [254]

Answer:

c 3

Step-by-step explanation:

the y intercept is where the line crosses the 0 x-axis

So ask yourself, what is the y when the x is 0?

on this one, the line crosses the 0 x-axis at 3 y

when the x is 0, the y is 3

So thats the y intercept

Thermometer A shows the temperature in the morning. Thermometer B shows the temperature in the evening. What is the difference i

Evgesh-ka [11]

Answer:

(Thermometer B reading - Thermometer A reading)

Step-by-step explanation:

The thermometer reading aren't given in the question.

However, hypothetically.

The difference between two temperature values (morning and evening values) would be :

Temperature in the evening - morning temperature

Therefore,

If ;

Thermometer A reading = morning temperature

Thermometer B reading = evening temperature

Difference in the temperature :

(Thermometer B reading - Thermometer A reading)
