Answer:
Explanation:
Slope is expressed as
Slope, m= change in value of y on the vertical axis / change in value of x on the horizontal axis.
change in the value of y = y2 - y1
Change in value of x = x2 -x1
Looking at the given points, (-3, 1), (-4, -2)
y2 = final value of y = - 2
y 1 = initial value of y = 1
x2 = final value of x = - 4
x1 = initial value of x = - 3
Slope = (- 2 - 1)/(- 4 - - 3)
Slope = - 3/- 1 = 3
Therefore, the first step to writing an equation in slope-intercept form using the given points: (-3, 1), (-4, -2) is
B) Find the slope using the slope formula
y2 - y1
x2 - x1
m = 3
