Answer:
I think it is 22 but I might be wrong.
Step-by-step explanation:
Answer:
The equation of this line is y = -1/4x - 7/2
Step-by-step explanation:
To find this, we need to first look for the slope. Perpendicular slopes have opposite and reciprocal slopes. Since the original line has a slope of 4, this means the new one has a slope of -1/4.
Given that slope, we can find the equation by starting with the base form of point-slope form.
y - y1 = m(x - x1)
Now put the slope in for m and the two coordinates in for (x1, y1).
y - 3 = -1/4(x - 2)
Now that we have this, solve for y for the slope-intercept form.
y - 3 = -1/4x + 1/2
y = -1/4x + 7/2
Answer:
(-3, 0)
Step-by-step explanation:
Dilation means that the position of the point is scaled up or down. Simply multiply the coordinates by the scale to get the new position.
w' = 3/2 w
w' = (3/2 × -2, 3/2 × 0)
w' = (-3, 0)
Divide both sides by the number in front of x
so
4x=-16
x=-4
12=-3x
x=-4
-21=7x
x=-3
6x=-30
x=-5
