7x + 2y = 10
How do I find the slope?

Slope is:

y = -7/2 x + 5

Step-by-step explanation:

7x + 2y = 10                 You need to get the y by itself on the left

-7x  + 2y = -7x     Subtract the 7x on both sides. The -7x cancels on the left

2y = -7x + 10        You need to get the y by itself on the left. Divide the 2 to                          

--- = +       each component. ( Everything on both sides )

2   =  2   + 2

y = -7      + 5         The 2's on the left would cancel. Divide for the rest

      x                Do not turn the -7 / 2 to a decimal! Keep it as it is!

      2

The linear equation is:

y = mx + b

y = y-value from coordinate

m = slope

x = x-value from coordinate

b = y - intercept

M = -7/2

We do not know what x and y is

b = 5

Hope this helps!!

a c

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
