Answer:
Step 1:
Find the vertex. Since the equation is in vertex form, the vertex will be at the point (h, k).
Step 2:
Find the y-intercept. To find the y-intercept let x = 0 and solve for y.
Step 3:
Find the x-intercept(s). To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form).
Step 4:
Graph the parabola using the points found in steps 1 – 3.
Step-by-step explanation:
Answer:
Slope intercept formula= y=mx+b
Step-by-step explanation:
m is the slope of the line and b is the y intercept
in this case b=5
y=mx+5
now, to get to the next point, we find our slope. rise/run
we rise 4 and run 1
y+4/1x+b
Answer:
189
Step-by-step explanation:
You can replace the values of x with 9 and the values of y with (-3).
7(2x-3y) = 7(2 × 9 - 3 × -3)
= 7(18 - -9)
= 7(18+9)
= 7 × 27
= 189
