can you help me with math please.

Question

Find an equation of the line that satisfies the given conditions.
x-intercept 1; y-intercept −3

Answer 1

x-intercept 1 means (1,0) is on the line.

y-intercept -3 means (0,-3) is on the line

 

slope: m = (change in y)/(change in x)

m = (-3-0)/(0-1) = -3/-1 = 3

 

slope intercept form: y = mx + b

m = 3, b = -3

 

y = 3x - 3

 

Answer 2

x-intercept of 1 means that (1, 0) is a point on the line. The y intercept is (0, -3)

 

The slope is found by (-3-0)/(0-1)= -3/-1 = 3

In the slope-intercept form y = mx + b, m stands for the slope, and b stands for the y intercept.

 

y = 3x -3
