Answer:
y = x + 8
Step-by-step explanation:
find slope first:
m = 7-5 / -1-(-3)
m = 2 / 2
m = 1
now find the y-intercept using either ordered pair; plug 'y', 'x', and 'm' into
y = mx + b to solve for 'b'
7 = 1(-1) + b
7 = -1 + b
8 = b
put 'm' and 'b' into slope-intercept equation of a line, y = mx + b to get:
y = x + 8
You may use direct substitution to solve for x and y.
So, x=2 and y=4.
Answer: <u>No</u> the expressions <u>are not</u> equal
Work Shown:
3² = 3*3 = 9
3³ = 3*3*3 = 27
3²+3³ = 9+27 = 36
3⁵ = 3*3*3*3*3 = 243
The 3²+3³ = 36 doesn't match up with 3⁵ = 243
Therefore, the two expressions are not equal.
