Answer:
y = (-8/9)x + 0.77777
Step-by-step explanation:
We already know the slope, so the only thing left to find is the y-intercept.
To find the y-intercept, we can plug in the slope and point to the slope-intercept form equation (y = mx+b, where m=slope and b=y-int.)
y = m * x + b
(7) = (-8/9)*(-7) + b
Now, just solve for b!
(7) = (-8/9)*(-7) + b
7 = 56/9 + b
7 - (56/9) = b
b = 0.777777 (repeating decimal, usually signified by a little line above the 7)
so now we just plug in the slope and y-intercept we found into y = mx + b.
y = mx + b
y = (-8/9)x + 0.77777
Answer:
Use the two point formula to find the equation of the line through two given points (x, y) and (X² X¹) is y-y¹/x-x² = y²-y¹/x²-x¹
