The equation of a line is y = mx + b. The variable m is the slope, so m = 2/3, giving you the equation y = (2/3)x + b. To find b (the y-intercept), plug in the given x and y values. So, it'll look like this: (-3) = (2/3)(7) + b. Finally, solve algebraically for b:
Multiply 2/3 by 7.
-3 = 14/3 + b
Subtract 14/3 from both sides.
-23/3 = b
The final equation is y = (2/3)x - 23/3.

Kristoff rents a kiosk in the mall to open an umbrella stand. He pays $3 to the mall owner for each umbrella he sells. The amount Kristoff pays is given by f(x) = 3x, where x is the number of umbrellas sold. Graph the function and give its domain and range.
Step-by-step explanation:
Answer:
slope = 2/5 , y-intercept = -30
Step-by-step explanation:
-2x + 5y = -30
5y = 2x - 30
y = 2/5x - 6
we know that the general form is:
y = (slope)*x + (y- intercept)
so, from our equation, we can say that...
slope = 2/5
y- intercept = -30
The answer will be: 538
