Answer:
The line crosses the y-axis at -2
Step-by-step explanation:
y = mx + b 'm is the slope and b is the y-intersect (the place where the graph comes across the y-axis.
y = mx + b; y = mx + b; b = -2.
One way to find the y int is to sub in 0 for x and solve for y
10x + 9y = 45
10(0) + 9y = 45
9y = 45 ...divide both sides by 9
y = 45/9 which equals 5
Multiply 6 and 8 which is 48cm
