Step-by-step explanation:
Answer:
x = -7/5 y = -6/5
Step-by-step explanation:
System:
y = -2x-4
AND
y= 3x+3
therefore -2x-4 = 3x+3
-2x-3x = 3 + 4
-5x = 7
x = -7/5
y = 3(-7/5) + 3 = -21/5 + 3 = -6/5
Mmmmmmmmmmmmmm mmmmmmmmmmmmm
Answer:
Step-by-step explanation:
In similar polygons, corresponding sides are in proportion.
Scale factor k = = 5 : 2
Answer:
The perpendicular line would be y = -2/3x - 9
The parallel line would be y = 3/2x + 21/2
Step-by-step explanation:
Since we have the slope of 3/2, we know the perpendicular slope will be -2/3. This is because perpendicular lines have opposite and reciprocal slopes. Now we can use that and the point in point-slope form to get the equation.
y - y1 = m(x - x1)
y + 3 = -2/3(x + 9)
y + 3 = -2/3x - 6
y = -2/3x - 9
For the parallel line we would use the same slope as the original (3/2) and also start with point-slope form.
y - y1 = m(x - x1)
y + 3 = 3/2(x + 9)
y + 3 = 3/2x + 27/2
y = 3/2x + 21/2
