#y=(2/23)x+2#

Explanation:

I will solve for slope intercept form, #y=mx+b#

To find the equation given two points, I would use the slope formula to find the slope first

#m=(y_2-y_1)/(x_2-x_1)#

#m=(0--2)/(23-0)=2/23#

You do not have to find #b# because it is the #y#-intercept, which we already know is #(0,2)#

#y=(2/23)x+2#

#color(indigo)(2x - 23y = 46, " is the equation in standard form"#

Explanation:

#A (0, 2), B (23, 0)#

Equation of #bar(AB)# is given by the formula

#(y - y_a) / (y_b - y_a) = (x - x_a) / (x_b- x_a)#

#(y - 2) / (0 -2) = (x - 0) / (23 - 0)#

#(y-2) / -2 = x / 23#

#23y - 46 = -2x, " Cross multiplying,"#

#color(indigo)(2x - 23y = 46, " is the equation in standard form"#
