Answer:

-2/5

Step-by-step explanation:

Slope is rise over run according to my former algebra teacher, but I learned it differently (still correct tho).

The first moves 2 units down so negative 2, and moves 5 units right, so -2/5 since the rise is -2, and run is 5.

The second one moves 2 x-units for every 1 y-unit, so the slope is 2,

Equation in slope intercept form between points (1,-4) and (0,6)?

Vinvika [58]

Find the gradient:
m = y2-y1 / x2-x1
m = 6-(-4) / 0-1
m = 10 / -1
m = -10

Slope intercept form:
y = mx + c

Input the values from one of the points to find c (imputing (1,-4) to y=mx+c):
-4 = -10(1) + c
-4 = -10 + c
c = -4 + 10
c = 6

Therefore, the equation is:
y = -10x + 6
