Answer:
y = -3x
Step-by-step explanation:
The standard expression of equation of a line in slope-intercept form is expressed as;
y = mx+c
m is the slope
c is the intercept
Given
slope m = -3
Point (x, y) = (-1, 3)
x = -1 and y = 3
Get the intercept
To get the intercept c, we will substitute the given values into the equation above to have;
y = mx+c
3 = -3(-1)+c
3 = 3 + c
c = 3-3
c = 0
Substitute m = -3 and c = 0 into the equation above;
y = mx+c
y = -3x+0
y = -3x
Hence the required linear equation is y = -3x
Step-by-step explanation:
The linear equation in slope intercept form of the lines that passes through (1,3) and (-3,-5) is y = 2x + 1
The slope intercept form is represented as follows:
where
m = slope
b = y-intercept
let's find slope:
(1, 3)(-3, -5)
m = -5 - 3 / -3 - 1 = - 8 / -4 = 2
Therefore,
let's find b using (1, 3)
y = 2x + b
3 = 2 + b
b = 1
Finally, the linear equation in slope intercept form will be as follows:
