point slope form y-y1=m(x-x1)
y-(-1) =5(x-(-2))
y+1 = 5(x+2)
to get it into slope intercept form
distribute
y+1 = 5x+10
subtract 1 from each side
y = 5x+9
Answer:
y = 5x + 9
Step-by-step explanation:
The equation of a line in its standard form can be written as:
y = mx + c
where y is the y coordinate,
m is the gradient of the line,
x is the x coordinate; and
c is the y intercept.
We will substitute the values of x and y coordinates and the slope to find the y intercept.
y = mx + c
-1 = (5) (-2) + c
c = 9
Therefore, the equation of the line which passes through the point (-2, -1) and has a slope of 5 will be y = 5x + 9.

Answer:
Meters
Step-by-step explanation:
Miles are to big to measure the distance of a city block, and inches are too small.
If she were to use inches, the number of the measure would be too large, and not easy to imagine and of she were to use miles, it would be a little number (like a fraction or decimal number), that wouldn't be as easy to understand. Instead, using meters, the measurements wouldn't be too little or to big, they would be between 50 or 150 meters on average, so these are numbers more usable and practical.
Answer:
Step-by-step explanation:
The city planner should use distance to measure the city block
-perpendicular bisectors of the sides
-bisectors of the angles
-medians
-lines containing the altitudes
Answer:
perpendicular bisectors of the sides: circumcenter
bisectors of the angles: angle bisector
medians: centroid
lines containing the altitudes: orthocenter
Step-by-step explanation:
perpendicular bisectors of the sides: circumcenter
bisectors of the angles: angle bisector
medians: centroid
lines containing the altitudes: orthocenter
