There are infinitely many lines that have the point (1,-3).
A line can be expressed as:
y=mx+b, where m=slope and b=y-intercept..
Our only restriction is that it passes through (1,-3) so
-3=1m+b
So as long as the sum of the slope and the y-intercept is equal to -3, that is one of the infinite number of lines that passes through (1, -3)
So we could also say b=-3-m then our infinite lines are:
y=mx-3-m, now any real value of m creates a specific line that passes through the point. ie the first few are
y=x-4, y=2x-5, y=3x-6 or even y=x√2-3-√2
Answer:
35
Step-by-step explanation:
Since the triangles are similar, we can write a ratio
25 ?
---- = -----
5 7
Using cross products
25*7 = 5 ?
Divide each side by 5
25*7/5 = 5?/5
35 = ?
Answer:
f\left(x\right)=\frac{1}{x^2}
Step-by-step explanation:
Answer:
x ≤ 4
Step-by-step explanation:
Subtract 7 on both sides:
x + 7 ≤ 11
-7 -7
x ≤ 4
