Line L's slope intercept form is
y = 4x + 7
It's point slope form is
y - 3 = 4 (x - -1)
You can check the point slope form and match it with the slope intercept form:
y - 3 = 4 (x - -1)
y - 3 = 4x + 4
y = 4x + 7
y = 4x + 7 = y = 4x + 7
The formulat for finding the slop is
m = (y2 - y1)/(x2 -x1)
so if we put the values of our two given points
m = (-13 -12) / (5 - 5) = -25/0 = undefined
so our slop is undefined which means it is a vertical line
Answer:
Step-by-step explanation:
(-1,5) (0,2)
y2= 2, y1 = 5, x2 = 0, x1 = -1
Slope m = [y2 - y1]/[x2 - x1]
m = {2 - 5}/{0+1}
m = -3/1
m = -3
And
y - y1 = m(x - x1)
y - 5 = -3(x + 1)
y - 5 = -3x - 3
y = -3x - 3 + 5
y = -3x + 2
Answer:
x - 4 = 2y
Step-by-step explanation:
"four less than a number x" therefore; x - 4
"is twice another number y" therefore; 2y
