Answer:
y - 2 3/7 (x-4)
Step-by-step explanation:
A) To find slope, use the equation:where Β and Β are the x and y values of one coordinate point Β , and Β and Β are the x and y values of another coordinate point . Since we are given two coordinate points, (-3,-1) and (4,2), that means we can find the slope using the slope equation. Β
Let's choose (4, 2) as your Β point and (-3, -1) as your Β point, but you can switch those if you want! That makes Β and x^1 = -3, y1 = -1 . Plug these values into the slope equation:
The slope of the line is 3/7.
B) Remember that the general equation for point-slope form is, where m = the slope, Β = the x value of a coordinate point on the line, and Β = the y value of the same coordinate point on the line. Β
You are given (4, 2) as one of the coordinate points. That means Β = 4 and Β = 2. We found the slope, m = Β in part A. Now plug these values into the general equation for point-slope form to find your point-slope form equation:
Your point-slope form equation is y - 2 3/7 (x-4).
Answer:
a. 3/7 b. y=3/7x+2/7
Step-by-step explanation:
(-1-2)/(-3-4)=3/7
slope is 3/7
