Answer:
Slope - intercept form
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the point (2,-4) and slope
Equation of the straight line passing through the point (x₁, y₁) and slope 'm'
y - y₁ = m( x-x₁ )
y - (-4) = ( x-2)
⇒ 5( y+4) = 3(x-2)
⇒ 5 y +20 = 3x -6
⇒ 3x - 5 y -6-20 =0
⇒ 3 x -5y -26=0
<u><em>Step(ii):-</em></u>
Slope - intercept form
5 y = 3x -26
if x is a regular cip of coffee and y is a large cup of coffee. the first part of the equation being the number of the cups of coffee and the second part expressing the price. using the method of substitution we solve for x in the first equation
x= 5-y
and then we solve for y
then we substitute the value found in the easiest equation which would be the first one and we solve for x
x + 2 = 5
x + 2 - 2 = 5 - 2
x = 3
so its 3 regular cups and 2 large
