I notice that all the choices are written in Point-Slope Formula. This is a key factor in answering your question. 

So usually we solve for slope, plug into point-slope form, then solve for slope intercept.

We only have to do the first 2 steps: 

Formula for slope: \frac{y2-y1}{x2-x1}
Plug in values: \frac{-4-2}{-1-(-6)} =  \frac{-6}{5}
Slope: - \frac{6}{5}
Point-slope formula: y - y1 = m(x-x1) where m is equivalent to slope. 
Plug in values: y -2 =  -\frac{6}{5}(x + 6) 


We can also rewrite the equation like this using the other coordinates. 

Plug in value: y + 4 = - \frac{6}{5}(x + 1)

What is an equation of a line,in point-slope from, that passes through (1, -7) and has a slope of -2/3
il63 [147K]

Answer:

y + 7 = - \frac{2}{3}(x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

Where m is the slope and (a, b) a point on the line

Here m = - \frac{2}{3} and (a, b) = (1, - 7), thus

y - (- 7) = - \frac{2}{3}(x - 1), that is

y + 7 = - \frac{2}{3}(x - 1) ← in point- slope form

Which ordered pair is a solution of the equation?<br> y=4x−7
vampirchik [111]

Answer:

Unknown

Step-by-step explanation:

Hi! so you didn't add the ordered pair options but I will do my best :) so if you see the ordered pair (0.7) that could definitely be a solution because using the slope intercept form equation you gave I know that's our y Intercept. the slope is 4/1 so moving up 4 and to the right 1 or down 4 and to the left 1 on a graph could show you more points! If you don't want to draw it you could use Desmos and just put this equation in or give me the ordered pairs and I will give you your answer!

hope this helps :)

winnie and kevin like to create their own triathlon courses to challenge each other. last weekend, winnie created a course that
shepuryov [24]
If you add all of the numerators together
3+57+13= 73
Then you would divide that number by 4
73/4= 18.25
So the course would be 18.25 or 18 1/4 miles long.
