Answer:
true
Step-by-step explanation:
Answer:
y = 120
Step-by-step explanation:
y = kx ur finding k
8 = k 3 get k alone by dividing both sides by 3 --> 8/3 = k
k = 8/3
Y = 8/3 45 now your finding Y when x is 45
Y = 120
to make sure do 120 = 8/3 45 should equal the same

Each of the lines lengths multiply by 3.
Hey there!
First, let's look at what perpendicular means. Imagine a cross, where there's all 90 degree angles. That's exactly what we're talking about when we say perpendicular. The given equation is in slope-intercept form, where we have:
y = mx + b
where m is the slope and b is the y-intercept.
When we're writing an equation with a perpendicular slope, we use the negative reciprocal of the given slope. Thus, we can make 0.3 1/3, and take the reciprocal to make 3, and make it negative 3 as it's the negative reciprocal. Now, we know we have a line with the slope of -3 and goes through (-3, 8). We can use the x and y values in this set of points, along with the slope, to create an equation to solve for b. That gives us:
8 = -3(-3) + b
8 = -9 + b
17 = b
Now, since we have slope and y-intercept, we can write our equation as:
y = -3x + 17
Hope this helps!
