d = sqrt(170)

d= 13.04 units

Explanation:

To find the distance between points at (1,4) and (-6,-7)

we can use the distance formula

d = sqrt((y_2-y_1)^2 + (x_2-x_1)^2)

for the points given
x_1 = 1
y_1 = 4
x_2 = -6
y_2 = -7

plugging in the values we get
d = sqrt((-7-4)^2 + (-6-1)^2)

simplifying the parenthesis
d = sqrt((-11)^2 + (-7)^2)

Simplifying the squares
d = sqrt(121 + 49)

simplifying the radical
d = sqrt(170)

d= 13.04 units
