The answer is a -4 (-16=4x)
(2,-1)(8,4)
slope = (4-(-1) / (8-2) = (4 + 1)/6 = 5/6
y - y1 = m(x - x1)
(8,4)...x1 = 8 and y1 = 4
slope(m) = 5/6
now we sub
y - 4 = 5/6(x - 8) <==point-slope form
y - 4 = 5/6x - 20/3
y = 5/6x - 20/3 + 4
y = 5/6x -20/3 + 12/3
y = 5/6x - 8/3
-5/6x + y = - 8/3...multiply by -6
5x - 6y = 16 <==standard form
Answer:
slope = 3; y-intercept = 6
Step-by-step explanation:
The y intercept is where the x value is zero
x=0 and y =6 so the y intercept is 6
We can find the slope from
m = (y2-y1)/(x2-x1)
= (9-6)/(1-0)
= 3/1
The slope is 3
Answer is t>7
5 Add 5 in both sides
