I NEED HELP ASAP Write an equation in point-slope form with the given characteristics Passes through (1,8) and (-2,3)

Step-by-step explanation:

1) Use the slope formula, , and the given points to find the slope. and represent the x and y values of one point the line must intersect, and and represent the x and y values of another point the line must also intersect:

=

=

2) Using the point-slope formula, , use the slope you just calculated and substitute it for m. Choose any of the two points given (I chose (1,8)) and substitute its x and y values for and . Don't worry, the equation of the line is the same no matter which point you choose (unless the question specifies which one you need to choose):

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
