SOLUTION: How do I write an equation for: with x intercept 4 and y intercept 5

An equation of a straight line in a coordinate plane in the slope-intercept form is 

    y = mx + b.   (1)



You need to find the parameters "m" and "b" from the given data.



For it, you need to know that y-intercept is the value of "b".

"y-intercept 5"   means  b= 5.


You also need to know that x-intercept is the value of x, which makes "y" equal to zero in the equation (1).

"x-intercept 4"   means  0 = m*4 + 5,  which implies m = .


Now the final equation of the line is  y = .     ANSWER
