Answer:

y= -7x-8

Step-by-step explanation:

The slope intercept form is y = mx + b.  

First, find the slope.  Use rise/run which gives you -7.  <= negative bc its a negative slope.  

Next, find the y intercept for b.  It is -8.  

Now, combine the numbers.  y = -7x-8.

What is an equation of the line that passes through the points (-1, -6) and (6, 1)?
Agata [3.3K]

Answer:

Step-by-step explanation:

It is vital  to first find the gradient/ slope between the points

m=\frac{y2-y1}{x2-x1} \\=\frac{1-(-6)}{6-(-1})\\ \\m=1

let us use the point (6,1) to find the value of c

y=mx+c

1=1(6)+c

1-6=c

∴c=-5

the equation is given by

y=x-5

Dominick is training for a race. He spends 0.75 hours running each time he runs and 1.5 hours swimming each time
umka2103 [35]

Answer:

The possible graph is "A". A further explanation is given below.

Step-by-step explanation:

The given values are:

Dominick spends on running

= 0.70 hours

He spends on swimming

= 1.5 hours

This week,

Dominick spends more than six hours.

If,

Number of runs be "x".

Number of swimming be "y".

then,

⇒ 0.75x+1.5y>6

⇒ 75x+150y>600

⇒ x+2y>8

Therefore, x+2y=8

x = 0

y = 4

So the above is the correct answer.
