Question

A line passes through point (3, 7) and has a slope of . The equation of the line is . If point A(x, 5) lies on the line, the value of x is . NextReset

Answer 1

3,7 = 7 * 3 = 21 * 5 = 105 so the next reset is 105. Hope I helped and god bless you and have a wonderful day.. 

Answer 2

(a) y = 3/4*x + 19/4

(b) x = 1/3

Explanation:

Assumption: line slope (m) is 3/4

(a)

Line general formula is y = m*x + b. In this exercise, you knew a point which lies on the line and its slope. So, replacing in the formula and solving for b gives

7 = 3/4*3 + b

b = 7 - 9/4

b = 19/4

Then, the equation of the line is y = 3/4*x + 19/4

(b)

Replacing the point into the formula obtained previously and solving for x gives

5 = 3/4*x + 19/4

x = (5 - 19/4)*4/3

x = 1/3
