Question

IF YOUR GOOD AT MATH THEN PLEASE ANSWER THIS ASAP

Which equation, expressed in standard form, represents the line on the graph?


A: 7x-4y=53

B: 5x+14y=39

C: 7x+4y=-53

D: 5x-14y=-39

Answer 1

D. X intercept is -39/5 or almost -8. Slope is 5/14 so line goes up.

Answer 2

D

Explanation:

Slope:

Point 1 = (-8,0) ---> x1 = -8 & y1 = 0

Point 2 = (6,5) ---> x2 = 6 & y2 = 5

(y2-y1)/(x2-x1)

(5-0)/(6-(-8))

5/14

Slope: 5/14

Point Slope Equation:

Equation: y - y1 = m(x - x1)

y - 0 = 5/14(x - (-8) )

y - 0 = 5/14(x + 8)

y = 5/14x + 2.85714285714

y = mx + b Form:

y = 5/14x + 2.85714285714

Standard Form:

y = 5/14x + 2.85714285714

5x-14y=-39
