(help me) What is the equation of the graphed line? https://static.k12.com/nextgen_media/assets/8080350-NG_IMC_SemA_03_UT_04.png Enter your answer in slope-intercept
Use the two given points to find the slope slope=\(\huge\frac{y_2-y_1}{x_2-x_1}\)
2 points on the line are given. Please find the slope of the line from them. Your slope will be approx. equal to -1. Find the exact slope.
how
y = mx + b m = slope b = y-intercept, which is where the line intersects the y-axis
I gave the slope formula above. Use that to find the slope @xgamer7868
Now write out the general slope-intercept formula for the graph of a straight line: y=mx+b. Substitute your slope value (m) into this equation. Next, choose one (not both) of the given points, and substitute its x-and y-coordinates into this same equation. this will enable you to find the value of b, the y-intercept. Pls show all your work.
ok
@mathmale they give the y-intercept, so @xgamer7868 doesn't need to solve for it
im confused
You have two points (0,7) and (8,.2) right? plug those into the given slope formula
ok
I agree: the y-intercept is given and is (0,7) Find the slope, then write the equation in slope-intercept form, with b=7.
so i change the numbers 1 and 2 to the points like y7 - y1 like that? x-2 - x8
No with two points \((x_1,y_1)\) and \((x_2,y_2)\)
So 0 = x1, 7=y1, and so forth
ohhh btw i meant 0 where i put 1
Two points (0,7) and (8,-2). Plug into slope formula: \(\Large\frac{-2-7}{8-0}\)
but i need the equation of the graphed line tho
I know. y = mx + b is the equation m = slope, so you need to find it b = 7
i gtg soon hurry
