The line drops 4 units between the points (1, 6) and (6, 2) as it goes over 5 units. Thus the point-slope form of the equation can be written as
... y - k = m(x - h) . . . . . . line with slope m through point (h, k)
... y - 6 = (-4/5)(x - 1)
Multiplying by 5 and subtracting the right side gives ...
... 5y - 30 = -4x +4
... 4x + 5y - 34 = 0 . . . . . equation in general form
Answer:
11/4
Step-by-step explanation:
To find the slope of a line given two points, we use the formula
m = (y2-y1)/(x2-x1)
= (-10-12)/(-7-1)
=-22/-8
=11/4
Y - y₁ = m(x - x₁) slope(m) = 3 point (1, 4)
y - 4 = 3(x - 1)
y - 4 = 3x - 3
y = 3x - 3 + 4
3x - y = -1 <<< your answer
hope this helps, God bless!
Answer:
45
Step-by-step explanation:
Substitute i = 1, 2, 3, 4, 5 into the expression and sum the terms
3(1) + 3(2) + 3(3) + 3(4) + 3(5)
= 3 + 6 + 9 + 12 + 15
= 45
Answer:
x = 40
Step-by-step explanation:
1/2x - 18 = 2
1/2x = 2 + 18
1/2x = 20
x = 20 / 1/2
x = 20 * 2/1
x = 40
