Find, in the form y=mx +c, the equation of the straight line with the given gradient which passes through the given point. gradient 3, point (1,2)

gradient -1, point (5,3)

gradient 4, point (-2,-3)

for first

Step-by-step explanation:

here

slope (m)=3

point=(1,2)=(x1,x2)

equation of straight line

(y-y1)=m(x-x1)

or 3x-y+1=0

so y= 3x+1

now do all of the question like this

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
