[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
Step-by-step explanation:
choose two point of A, let k(-2, -3) and l(1, 3)
[tex] m = \frac{ - 3 - 3}{ - 2 - 1} = \frac{ - 6}{ - 3} = \frac{1}{2} [/tex]
choose two point of B, let c(0, 5) and d(5, 0)
[tex]m = \frac{5 - 0}{0 - 5} = \frac{5}{ - 5} = - 1[/tex]
Hence the gradient of A is
[tex] \frac{1}{2} [/tex]
and B is -1
Find an equation in point-slope for the line having the slope m m = - 6 and containing the point (8,6)
Answer:
y-6 = -6(x-8)
Step-by-step explanation:
Here, we want to get the equation of the line in point-slope form
The point slope form is;
y-y1 = m(x-x1)
(x1,y1) represents the slope
We have this as ;
y-6 = -6(x-8)
3. What are the factors in the expression 4(5 + x)?
Answer:
Step-by-step explanation:
The factors are the parts that are being multiplied together.
4 and (5+x) are the two that are being multiplied and also the expression you get when you factor the distributed expression.
So the factors of 4(5+x) are:
4 and (5+x)
solve the equation for y: 2x+3y=6
Answer:
Let's solve for x.
2x+3y=6
Step 1: Add -3y to both sides.
2x+3y+−3y=6+−3y
2x=−3y+6
Step 2: Divide both sides by 2.
2x 2 =
−3y+6
2 x= −3
2 y+3
Answer:
x= −3 2
