(2.5,150)(4,240)
slope = (240 - 150) / (4 - 2.5) = 90 / 1.5 = 60
y = mx + b
slope(m) = 60
(4,240)...x = 4 and y = 240
now we sub and find b, the y int
240 = 60(4) + b
240 = 240 + b
240 - 240 = b
0 = b
so ur equation is : y = 60x + 0 which is written as : y = 60x <==
Answer:
B.) 2. 8-6=2 thanks for watching
Step-by-step explanation:
let eqn be y = mx + b.
3y = x - 15
y = 1/3x - 5
perpendicular means product of grad = -1
hence m = -3.
sun (8, 0):
8 = -3(0) + b
b = 8
therefore, equation if the line is y = -3x + 8

If you have a table that tells you the (x,y) or coordinates on a graph you can take those coordinates and insert them into the equation y=mx=b. this is the equation to find the slope of a line. If you solve for b in the equation you will have the y intercept. the mx would be the slope.
