Answer:
Given line with an equation of y = 4x + 3
Parallel lines contain equivalent slopes, so a parallel line to the given equation would contain a slope of m = 4.
Plug in the coordinates of the point given, along with the slope into the equation y = mx + b where:
m = slope
y = y-coordinate of point
x = x-coordinate of point
Solve for the 'b' value, or y-intercept:
y = mx + b
6 = 4(2) + b
6 = 8 + b
b = -2
Rewrite the equation as slope-intercept form:
y = 4x - 2
Answer:
30- 3x 14
Step-by-step explanation:
Let say that Y is the number of toys you have now and X is the number of the customer. Every customer (X) buy 3 toys, and you have 30 toys at the start. So you can put this equation
30- 3x = Y
Now you have at least 14 toys, in other words, it is more than or equal to 14 (14). The equation will be:
30- 3x 14
