Answer:
y=-2x-1
Step-by-step explanation:
so we need to find y=mx+3
y=intercept
mx=gradient
c is the y intercept where it crosses the line the y and m axis is the gradient which means the slope of the graph to find c but you need to find m so the gradient has a formula and you need to use any of the coordinates
so the formula will be y2-y1 /x2-x1 this means you do the second y from the first y from the first coordinates do the same for x and then divide them y2-y1/x2-x1=-5--3/2-1=-5+3/1 so m=-2 to look for c we do -7=-2(3)+c =-7= -6 +c
=-7+6=c =-1=c
y=mx+c
ans= y=-2x-1
ik it long lol
