((-3,-10),(-1,-4),(0,-1),(2,5),(4,11)) in y=mx+b form
1 answer:
Answer:
y = 3x -1
Step-by-step explanation:
It is convenient to choose two points that have x-values 1 unit apart when computing the slope of the line (m). Here, we choose the points (-1, -4) and (0, -1).
... m = (change in y)/(change in x) = (-1-(-4))/(0-(-1)) = 3/1 = 3
The point (0, -1) tells you that the y-intercept (b) is -1.
Now you have the information you need to fill in y = mx + b:
... y = 3x -1

Answer:
see attached
Step-by-step explanation:
The given equation is in intercept form:
x/(x-intercept) +y/(y-intercept) = 1
This means the x- and y-intercepts are (4, 0) and (0, -3), respectively. Plot these points and draw the line through them.
