Step-by-step explanation:
Equation of a straight line
y = mx + c, m is the slope, and c the intercept
points (3,7) x = 3, y = 7, c = 1
7 = m × 3 + 1
7 = 3m + 1
3m = 7 - 1
3m = 6
m = 6/3
m = 2

Solve y: 6.3 = 0.9y
6.3/0.9 = 0.9y/09
y = 7
Solve x: x + 7.72 = 19
x + 7.72-7.72 = 19 - 7.72
x = 11.28
What is y? 7 What is x? 11.28
