Correct answer: <span>y=1/2x-5
</span>
given: point = (2,-4)
slope = 1/2
Explanation: equation of line is: y = mx + c
where, m is the slope
c is the y-intercept
Now,
here, y = 1/2x + c
put, x = 2, y = -4
we get, -4 = (1/2).2 + c
or c = -4 - 1
or c = -5
Hence, equation of line is : y = 1/2x-5
Answer:
-1/3
Step-by-step explanation:
y2-y1 divided by x2-x1
6-8=-2(y slope)
4--2=6(x slope)
-2/6=-1/3 or -0.3333
Answer:
C. y=0.5x+3
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let
x = the amount of time William has been digging
y = the amount he has left to dig
The hole has to be in 2 ft deep. This means when William starts, the hole was 0 feet deep and has left 2 ft to dig. Hence, y-intercept is
He is able to dig at a rate of ft per minute. Thus, the slope is (negative because the depth left to dig is decreasing).
The slope-intercept form of the equation is so in your case this equation is
