What is the equation, in slope-intercept form, of the line that contains the points (-1, 8) and (4, 3)?
a. y = -x + 7
b. y = x - 7
c. y = x - 1
d. y = 7x - 1

A

Step-by-step explanation:

To write the equation of a line, calculate the slope between points (-1,8) and (4,3). After, substitute the slope and a point into the point slope form.

Substitute m = -1 and the point (4,3) into the point slope form.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
