Please help me 1, 2, 3 or 4 I need it

I think it's 4

Step-by-step explanation:

y=mx+b is the formula

m=slope

b=y intercept

the slope is 2

and the y intercept is -3

so the answer is 4, y=2x-3

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

∠cbe and ∠deb are same-side interior angles.
