Answer:
The Slope is 9 and the y-intercept is -2
Step-by-step explanation:
Answer:
y - 4 =
(x - 7)
Step-by-step explanation:
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
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (7, 4)
m =
= 
Use either of the 2 points for (a, b)
Using (7, 4), then
y - 4 =
(x - 7) ← in point- slope form
Answer:
C: 1.5
Step-by-step explanation:
For point D, the y value goes from 4 -> 6. This means that 4x = 6 ,
.
For point F, both values (x and y) are multiplied by 1.5.
Answer:
Easy -2x
Step-by-step explanation:Because both a positive y and a negative y cancle out eachother so all thats left is both of the negative x's
