Answer:
The equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:
Step-by-step explanation:
The slope-intercept form of the line equation
where
In our case, we are given
The slope m = -1/2
Point (2, -3)
now substituting m = -1/2 and (2, -3) in the slope-intercept form of the line equation to determine the y-intercept
-3 = -1/2(2) + b
-3 = -1 + b
b = -3 + 1
b = -2
now substituting m = -1/2 and b = -2 in the slope-intercept form of the line equation
y = mx + b
y = -1/2x + (-2)
y = -1/2x - 2
Therefore, the equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:
Answer:
D
Step-by-step explanation:
Domain & Range is just x and y.
the function includes x values between & including -2 and 2, while y includes 3, and -3
T= -2
It is really simple, just subtract positive 7 from 5 in order to get T alone and get -2
Answer: -6
Step-by-step explanation:
ok so basically rate of change = slope or m
so take two set of points from the table and do the slope equation which is y2- y1 over x2 - x1 (i can't really do equations in brainly bc i'm new so sorry but u can search up the equation)
so in this case, let's do the points (3, -15) & (4, -21)
now let's plug those values into the equation
so - 21 + 15 = -6 and 4 - 3 = 1
now u would simplify or divide so -6 divided by 1 = -6 so that's it! hope this helps!
