What is the equation of the line that passes through the points (20,-3) and (0,2)?
1 answer:
Answer:
C
Step-by-step explanation:
Put the equation in the form y = mx + b where m is the slope and b is the y-intercept
First, find the slope by doing the change in y divided by the change in x for the two points. This would be . m = -1/4 in the equation.
So far, the equation is y = -1/4x + b
This means the slope is -1/4. Since it give you the y intecept, (0, 2), you know that b is 2 and the equation would be C. y = -1/4x + 2

to solve for y, we must multiply by t on both side to get ride of the t in the denominator. By doing this, we will get:
on the right side.
Subtracting 3, and we have successfully isolated y.
It would be impossible to get a quantitative value for y if we don't know the value of t.
