Find the missing value so that the line passing through the points (7, 1) and (x, 4) have the slope of 3/4 *

(7,1) and (11,4)

Step-by-step explanation:

(4-1)/(x-7)=3/4

3=3(x-7)/4

12=3(x-7)

4=x-7

11=x

Therefore, the missing x-coordinate is 11.

b

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 ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
