The line passing through (3, -1) and (-1, 5) has this slope:
5+1
m = ---------- = -3/2
-1-3
We need to find the y-intercept. To do this, substitute the knowns (-3/2 for m, -1 for y and 3 for x) into the slope-intercept equation:
-1 = (-3/2)(3) + b. Then: -1 = -9/2 + b, and so b = 9/2 - 1 = 7/2.
The desired equation is y = (-3/2)x + 7/2.
Answer:
Answer:
44 = 12 + M
Step-by-step explanation:
Start with your final amount that everything else is going to equal
44 =
Then, add the $12 that is already saved to the other side\
44 = 12
But, that equation is not true yet, so we have to add the amount of money that she still needs to save
44 = 12 + M
That equation shows that the money she has saved ($12), plus the amount she still has to save will equal the amount she needs.
