The slope-intercept form:
The formula of a slope:
We have the points (-4, 47) and (2, -16). Substitute:
Therefore we have:
Put the coordinates of the point (2, -16) to the equation:
Answer: 
Let the number be x and 2x-5 from the above given condition
x+2x-5=70
or
3x=75 s0 x=25
Hence, the number are 25 and 45
Answer:
f(x) = -3/7x - 6
Step-by-step explanation:
We knownthe equation of a line is y = mx + b. where m is slope and b is y intercept.
the point slope equation of a line is y - y1 = m (x - x1)
plug in x1 and y1 and m
y- (5) = (3)(x - (-1))
y - 5 = 3x + 3
y = 3x + 8
