a line passes through (9, –9) and (10, –5).write an equation for the line in point-slope form. rewrite the equation in standard
Cerrena [4.2K]
The equation of the line in point-slope form is given by:
 y-yo = m (x-xo)

 Where,
 (xo, yo): point that belongs to the line
 m: slope of the line
 The slope is given by:
 m = \frac{y2-y1}{x2-x1}
 Substituting values:
 m = \frac{-5-(-9)}{10-9}
 Rewriting:
 m = \frac{-5+9}{10-9}
 m = \frac{4}{1}
 m=4
 Now we choose an ordered pair:
 (xo, yo) = (10, -5)

 Substituting values we have:
 y-(-5)=4(x-10)
 y+5=4(x-10)
 We now rewrite the equation in its standard form:
 y = mx + b

 Where,
 b: cut with the y axis.
 We have then:
 y = 4x - 40 - 5

y = 4x - 45
 Answer:
 point-slope form:
 y+5=4(x-10)
 or
 y+9=4(x-9)
 standard form
 y = 4x- 45

Equation 2(4x − 11) = 10.
dedylja [7]
Since you didn't provide instructions, I am going to assune you are being asked to solve for x. To do this, just distribute and simplify.

2(4x-11)=10
Distribute the 2 to the expression (4x-11)
8x-22=10
Add 22 on both sides
8x=32
Divide by 8 on both sides
x=4

~I hope this helps!~
