Answer:
Slope = 2/3
Step-by-step explanation:
See the image attached below.
The red line represents the "run".
The blue line represents the "rise".
Slope = rise/run
Rise = 4 units
Run = 6 units
Slope = 4/6
Simplify
Slope = 2/3
the equation of a line in point-slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
to calculate m use the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 4, - 1) and (x₂, y₂) = (1 1/2, 2 )
m = = =
using (a, b) = (- 4, - 1), then
y + 1 = (x + 4)
the answer is -3 hope this helps
5x^2+2x-3=0
We can use the quadratic formula:
ax^2+bx+c=0; a=5, b=2, c=-3
x=[-b+-sqrt(b^2-4ac)]/(2a)
x=[-(2)+-sqrt((2)^2-4(5)(-3))]/[2(5)]
x=[-2+-sqrt(4+60)]/10
x=[-2+-sqrt(64)]/10
x=(-2+-8)/10
Two solutions:
x1=(-2-8)/10→x1=(-10)/10→x1=-1
x2=(-2+8)/10→x2=6/10→x2=3/5
Answer: x=-1 and x=3/5
Answer: Options D. x=-1 and F. x=3/5
