Can someone remind me how to do an equation like y=4x+3 i have a huge exam tomorrow

Solve each equation for y and then the slope is m and y-intercept is b as in:
So, if you do that, you'll get (remember, this is <em>after</em> solving for y):
1. m = -6, b = -2
2. m = 5, b = -1
3. m = -5/3, b = 5
4. m = 0, b = -1/4
5. m = -1, b = -3
6. m = 3, b = -4
7. m = 1/2, b = -5/2
8. m = 7/2, b = 1
Hope this helps.

Answer:
B
Step-by-step explanation:
Since the triangle is right use the tangent ratio to find x
tan64° = =
Multiply both sides by 11
x = 11 × tan64° = 22.55 → B
