Determine the slope of the line that passes through the points (-2, 5) (1, -7)
2 answers:
Answer:
slope is -4
Step-by-step explanation:
Find slope which is also referred to as m:
m = (y₂ - y₁) / (X₂ - X₁)
= (-7 - 5) / (1 - (-2)
= -12 / 3
m = -4
Not asked in question but if you want to find equation for the line:
Find b using any one of the two provided coordinates. Let's use (-2, 5).
y = mx + b
5 = -4(-2) + b
5 = 8 + b
b = -3
Use m and b to make equation.
y = mx + b
y = -4x - 3
Answer:
Step-by-step explanation:
<u>Given points </u>
<u>Use slope formula to find the slope</u>
- m = (y2 - y1)/(x2 - x1)
- m = (-7 -5)/(1 + 2) = -12/3 = -4
Slope is -4

What's the question that needs to be solved and I will help?
We know:x^2+y^2+x−6y+9=0So, we complete the square as such:x^2+y^2+x−6y+9=x^2+x+y^2−6y+9=(x+1/2)^2+(y−3)^2=(1/2)^2=1/4
